1. Lisa's parents gave her $1000 for her high
school graduation. She put the money into a
savings account that earned 7.5% annual
interest. How much interest will be paid after
nine months?

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.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
