(3y +10) /4 = 2y

Multiply both sides by 4:

4(3y +10) = 4(2y)

12y +40 = 8y

Subtract 40 from each side:

12y = 8y -40

Subtract 8y from each side:

4y = -40

Divide both sides by 4:

y = -40 / 4

y = -10

The answer is A. -10

A man borrowed $8000. He paid $10100 after 9 months for the debt. What was the interest rate per annum?

Anastaziya [24]

Answer:

3.5%

Step-by-step explanation:

Interest = 10100 - 8000 or 2100

I = Prt

2100 = 8000(9/12)r

2100 = 600r

2100/600 = r

3.5 = r
