If they are equivalent, you should be able to cross multiply and get a true statement.

12/30 = 48/120

12(120) = 30(48)

1440 = 1440

This is a true statement, therefore they ARE equivalent.

VladimirAG [237]

Answer:

The amount of money you will receive is $927.419

Step-by-step explanation:

Consider the provided information.

A youth group has a yard sale to raise money for a charity. The group earns $800 but decides to put its money in the  bank for a while.

We need to calculate the amount of money if hot bank pays an interest rate of 3% compounded annually, and the youth group leaves the money in for 5  years.

Future value can be calculated as:

FV=PV(1+r)^n

Substitute PV=800, r=0.03 and n=5 in above equation.

800(1+0.03)^5

800(1.03)^5=927.419

Hence, the amount of money you will receive is $927.419
