Jassie put 3,200 into a savings account that cam 3.5% annual com pound interest If she makes no other deposits withdrawals, what will her balance be ofter 12 year?

Step-by-step explanation:

r = 35 / ( 3200 × 12 ) = 0.00091146

r = 0.00091146

converting r decimal to a percentage

R = 0.00091146 * 100 = 0.0911%/year

The interest rate required solve for the  simple interest of $ 35.00

from a principal of $ 3,200.00

over 12 years is 0.0911% per year.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
