Answer: B) $4,000
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the loan.
P represents the principal or amount taken as loan
R represents interest rate
T represents the duration of the loan in years.
Considering Cathy's loan,
P = $20,000
R = 5.2%
T = 10 years
I = (20000 × 5.2 × 10)/100
I = $10400
Considering Steven's loan,
P = $20,000
R = 4.8%
T = 15 years
I = (20000 × 4.8 × 15)/100
I = $14400
The difference between the amounts of interest Cathy and Steven paid for their loans is
14400 - 10400 = $4000
Answer:
the answer is B $4,000
Step-by-step explanation: Apply the formula I = Prt, where I is interest, P is principle, r is rate, and t is time.
I = 20,000(
5.2
100
)(10) = 20,000(0.052)(10) = 10,400
I = 20,000(
4.8
100
)(15) = 20,000(0.048)(15) = 14,400
Therefore, 14,400 − 10,400 = 4,000
