A nursery has $60,000 of inventory in dogwood trees and red maple trees. The profit on a dogwood tree is 29% and the profit on a red maple tree is 17%. The profit for the entire stock is 20%. How much was invested in each type of tree?

Answers

Answer:

27g

Step-by-step explanation:

The invested amount dogwood tree is $15000 and on maple tree is $45000 as per linear equation.

What is a linear equation?

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line."

Given, total invested amount is $60000.

Let, invested amount for dogwood trees is $x.

Therefore, invested amount for maple trees is ($60000 - x).

Now, the profit on a dogwood tree is 29% = 0.29.

The profit on a red maple tree is 17% = 0.17.

Again, the profit for the entire stock is 20%. = 0.20.

Therefore,

(x + x × 0.29) + [(60000 - x) + (60000 - x) × 0.17 = 60000 + 60000 × 0.20

⇒ 1.29x + 60000 - x + 10200 - 0.17x = 72000

⇒ 0.12x = 72000 - 60000 - 10200

⇒ 0.12 x = 1800

⇒ x = 15000

Therefore, invested amount  on dogwood tree is $15000.

Similarly, invested amount on maple tree is $(60000 - 15000) = $ 45000.

  q = parallel lines intersect

The symbol ∨ is used to represent the disjunction (or).

The symbolic form of the given statement is ...

  p ∨ q

__

As it happens, both p and q are false, which means the disjunction is false. That has no bearing on the symbolic representation of it.

Assume a tax rate of 6.2% on $128,400 for Social Security and 1.45% for Medicare. No one will reach the maximum for FICA. Complete the following payroll register. (Use the percentage method to calculate FIT for this weekly period

Marital status - m
Allowance claimed – 4
Gross pay - $,2800
FIT
Social Security
Medicare
Net pay

Answers

Answer:

FIT: $340.76 (see comment)OASDI: $173.60Medicare: $40.60Net Pay: $2245.04

Step-by-step explanation:

In addition to the information given in the problem statement, we need to know the applicable tax rates and allowance deductions. If we assume the tables we found (attachments 1 and 2) are the same as those in your text, the one additional fact needed is the gross pay to date. At the given wage rate, paychecks after the 44th week will have reduced FICA tax deductions.

Allowances: 4 × $79.80 = $319.20

Adjusted gross pay for FIT: $2800 -319.20 ≈ $2481 (rounded to nearest $)*

FIT: 0.22 × (2481 -1711) +171.36 = 0.22×2481 -205.06 = 340.76

Social Security & Medicare: 0.0765 × 2800 = 214.20

Net pay = $2800 -340.76 -214.20 = $2245.04

_____

* Comment on rounding

The IRS gives the option of rounding the pay or the tax, as long as it is consistently done. Here, the amount of tax on the unrounded gross pay would be 4 cents less: 340.72. The option of reducing the last digit of pay to zero is also offered. FIT on 2480 would be 340.54.

Little wonder then, that the first thing most of us like to see when we pick up a newspaper is the cartoon. Simple though it may seem, making a cartoon is an art that requires a combination of hard work, training and a good sense of humour. Cartoonists say that the cartoons that make us laugh the most are in fact the cartoons that are hardest to make. Even celebrated cartoonists like R.K.Laxman admit that making a cartoon is not a piece of cake. Laxman says he has to wait for over six hours, which includes spending a lot of time scanning newspapers and television channels before any idea strikes him.So how does one become a cartoonist? Which of us has the talent to make it? How can we master the rib-tickling strokes and the witty one-liners? How can we make people smile or laugh? There are few colleges or schools for cartoonists. Most cartoonists come from art colleges, while some learn the craft on their own. Most established cartoonists are of the view that no institute can teach you to make a cartoon. "You can pick up the craft, you may learn to sketch and draw in institutes, but no one can teach anyone how to make a good cartoon," says Uday Shanker, a cartoonist with Navbharat Times. While basics, like drawing and sketching can be learnt in an art college, and are important skills, these alone, do not make a good cartoonist. Because it's a question of one's creativity and sense of humour; two qualities one simply may not have. The advice established cartoonists give is that just because you can sketch, don't take it for granted that you will become a cartoonist.
