Official Solution:
The rental charge for a car is 34 cents for the first \(\frac{1}{4}\) mile driven and then 6 cents for each additional \(\frac{1}{5}\) mile driven beyond the initial \(\frac{1}{4}\) mile. If a man paid $1.24 for rental charges, how many miles did he drive?
A. 2.50
B. 3.00
C. 3.25
D. 3.75
E. 4.00
To determine the additional miles driven beyond the first quarter-mile, we first subtract the charge for the initial \(\frac{1}{4}\) mile ($0.34) from the total charge ($1.24), which gives $0.90.
Dividing this by the rate of $0.06 for each \(\frac{1}{5}\) mile segment, we find the driver traveled 15 segments of \(\frac{1}{5}\) mile, or \(15*\frac{1}{5}=3\) miles. Including the initial \(\frac{1}{4}\) mile, the overall distance driven is 3.25 miles.
Answer: C
what's wrong with this equation:
0.34 * (1/4) + 0.06 (x- 1/4)/(1/5) = 1.24?
+ 0.06 * (x - 1/4)/(1/5) = 1.24 is in the first term.
This way, the first 0.34 accounts for the initial charge, and the remaining cost is based on the additional miles driven.
