Makayla borrows $15200. Some is from her friend at 5% annual interest, 2 times as much as that from her bank at 8% , and the remainder from her insurance company at 4%. She pays a total of $968 in interest for the first year. How much did she borrow from each source?
Answers
Answer:
Amount borrowed from friend = 4000
From Bank = 8000
From insurance = 3200
Step-by-step explanation:
Given that:
Amount borrowed = $15200
Let amount borrowed from friend = x
x at 5% = 0.05x
From Bank = 2x at 8% = 0.08*2x = 0.16x
From insurance = 15200 - (x + 2x) at 4%
From insurance = 15200 - 3x at 4% ; (15200 - 3x)* 0.04 = 608 - 0.12x
Interest paid in first year = $968
Simple interest = principal * rate * time
968 =
968 = (0.05x + 0.16x + 608 - 0.12x)
968 - 608 = 0.05x + 0.16x - 0.12x
360 = 0.09x
x = 360 / 0.09
x = 4000
Hence,
Amount borrowed from friend = 4000
From Bank = 2x = 4000 * 2 = 8000
From insurance = 15200 - (4000 + 8000) = 3200
two angles of a triangle measure 55° and 20°

Trevor went to the pet store to get a new pet fish. Unfortunately, the selection at the store wasn't very good. Exactly 90% of the fish at the store were goldfish. Trevor wanted any fish, but a goldfish. If there are 140 fish at the store, then how many fish could Trevor choose from?
Answers
Answer: 14 fish
explanation: 90% of 140= 126 (if u use a proportion or multiply 0.9x140).
140-126=14
Answer: He has 14 other fish to choose from in the store
Step-by-step explanation:
90% ÷ 100 = .9
.9 × 140 = 126
140 - 126 = 14

One number is three less than a second number. Six times the first is 6 more than 3 times the second. Find the numbers.
Answers
Step-by-step explanation:
Given,
x = y - 3
Also,
6(y - 3) = 3y + 6
6y - 18 = 3y + 6
6y - 3y = 6 + 18
3y = 24
y = 24/3
y = 8
x = 8 - 3
x = 5
Therefore, the first number is 5 and the second number is 8.

Q: How much money would you save on 10 pounds of blueberries at the less expensive fruit stand? (Hint: Find the cost of 10 pounds of blueberries for each, A and B, then subtract the values.) Remember to explain your reasoning!
Answers
Answer:
According to my...calculations, you would save $20.
Step-by-step explanation:
You have to find the ratio/the rate of change, then you multiply it to get to ten pounds. You do the same for the other line. Then you just subtract it.
A= 2 pounds for $12
B= 1 pound for $4
Multiply the two to get to 10, and whatever the number is (5) you multiply 12 by it as well. For B, you multiply by 10. You get $60, for A. $40 for B.
The amount saved would be $20.
