An art club sells 42 large candles and 56 small candles.
a. Write and simplify an expression that represents the profit.
expression for the profit: _(_-x)+_(_-y)
simplified expression for the profit: _______
b. A large candle costs $5, and a small candle costs $3. What is the club’s profit?
club's profit: $__

Answers

Answer:

Profit = $(700 - 42x - 56y)

Step-by-step explanation:

For large candles, the selling price is $10 and its making cost is $x.

So, by selling a large candle the profit is $(10 - x)

Again for small candles, the selling price is $5 and its making cost is $y.

So, by selling a small candle the profit is $(5 - y)

Therefore, in a sell of 42 large candles and 56 small candles the total profit will be, P = 42 (10 - x) + 56 (5 - y)

⇒ P = 420 - 42x + 280 - 56y {Applying distributive property}

⇒ P = $(700 - 42x - 56y) (Answer)

Step-by-step explanation:

Step-by-step explanation:

A carton of two dozen eggs includes three with cracks. How many eggs without cracks can be expected in six dozen eggs?

Answers

Answer:

63

Step-by-step explanation:

because 2 dozens is 24, and since there are three cracked eggs in two dozens, in six dozens, which is 72 eggs, since 24 times 3 is 72, we have to multiply 3 times 3, which is nine, so 9-72,which is 73.

The number of eggs without cracks can be expected in six dozen eggs will be 63.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A carton of two dozen eggs includes three with cracks.

Crack egg = 3 / (12 x 2)

Crack egg = 3 / 24

Crack egg = 1/8

The number of non-crack eggs is given as,

Non-crack egg = (24 - 3) / 24

Non-crack egg = 7/8

Then the total number of eggs in six dozen is given as,

Total egg = 12 x 6

Total egg = 72

Then the total number of non-crack eggs is given as,

Total non-crack eggs = 72 x 7 / 8

Total non-crack eggs = 63

The number of eggs without cracks can be expected in six dozen eggs will be 63.

There were 18 seeds planted in the garden. After one week there were 324 seedlings. After 2 weeks there were 648 seedlings. If the number of seedlings grows at the same rate each week, how many seedlings will there be after 5 weeks?

Answers

Answer:

The answer is 1620 seedlings.

Step-by-step explanation:

The rate is that every one week, there is an increase of 324 seedlings. If it continued for 5 weeks, the total amount of seedlings will be 1620 seedlings. The equations I used to solve this are 648-324=324. 324x5=1620.

324*5 is 1620, so the answer is 1620

Solve this equation y=bd-6, for b

Answers

To solve this equation, you would need to isolate b. To do this, first you would add six to both sides. Then, to get rid of the d, you would divide both sides by d since that is the opposite of multiplication. So, the answer would be

b = y-6
———
d

Answer:  [tex]b = \frac{y+6}{d}[/tex]

Step-by-step explanation:  To isolate b, begin by adding 6 to both sides

y=bd-6

y + 6 = bd - 6 +6   This "cancels" 6 on the right leaving

y + 6 = bd   Divide both sides by d

(y + 6)/d = bd/d   This cancels d on the right leaving

(y + 6)/d = b   To neaten this up rewrite (using the equations tool below)

[tex]b = \frac{y+6}{d}[/tex]
