Answer:
n=6
Step-by-step explanation:
1/2 n + 3 = 6
Subtract 3 from each side
1/2 n +3-3=6-3
1/2n = 3
Multiply each side by 2
1/2 n * 2 = 3*2
n = 6
You have the following equation for the cost of renting a car for x number of miles driven:
y = 0.15x + 65
If you travel 70 miles, then, x = 70 and you obtain for the cost y:
y = 0.15(70) + 65
y = 10.5 + 65
y = 75.5
Hence, the cost of renting a car to drive 70 miles is $75.5
