Answer:
S = $336
Step-by-step explanation:
<u>Given the following data;</u>
Principal, P = $600
Rate, R = 7
Time, T = 8 years
To find the simple interest?
Mathematically, it is given by the formula;
Simple interest, S = (P*R*T)/100
Substituting into the equation, we have;
S = (600*7*8)/100
Simplifying the equation, we have;
S = 6*7*8
S = $336
.35 = 35% because the number is out of 100, and the five is in the hundredths place
22 ÷ .10
=2.2
22 - 2.2 = 19.80
She had to pay $19.80.
