Answer:
11/12
Step-by-step explanation:
We will use the equation:
r t = 3/4 r ( t+12 ) /:r
t = 3/4 t + 9
t - 3/4 t = 9
1/4 t = 9
t = 9 * 4 = 36 minutes ( takes a trip to the market )
36 + 12 = 48 minutes
The ride home takes 48 minutes.
I = PRT/100
P = Principal, R = Rate, T = Time
I = 1500 * 7.5 * 1.5 /100
I = 168.75
Interest owed = $168.75
