Corlos bought a book for $9 . now he would like to buy 4 other books for the same price .how much will he have to pay in all for

Rashid [163]

I'd do 9x4=36 because the 9 is from your money and the 4 is from your books. Now since you want to find out how much 4 books cost you just multiply that by 9

Answer:

a) $336

b) $1036

Step-by-step explanation:

a) The interest is computed using the formula ...

I = Prt

where P is the amount invested at rate r for t years.

I = $700·0.08·6 = $336

The interest earned is $336.

b) The balance of the account is the sum of the original amount and the interest earned:

balance = $700 +336 = $1036

The balance of the account is $1036.
