1. Lisa's parents gave her $1000 for her high

Can someone explain this to me

$56.25

Step-by-step explanation:

Money: $1000

Interest: 7.5% or

There are two steps you can use to find this.

First

---------------------------------------------------------------------------------------------

To find the annual interest multiply by the rate.

We can now find how much that is per month;

per month, to find how much that is in 9 months, multiply by 9

----------------------------------------------------------------------------------------------

Second

You know 12 months is 1 year, you divide the amount of months that we're trying to calculate the interest of, by the amount of years in months; in this case, 12.

Multiply that by the interest and the total amount.
