Arabella Cervantes · Answer 1

3 rides.

Step-by-step explanation:

The correct answer is 3 rides as in the first ride your benefit is $25 while you will pay only $7.

For the second ride your additional benefit is $18 and again you will pay only the additional $7.

Likewise, for the third, the benefit $11 and the cost $7.

You will not consider the fourth ride because the additional benefit is only $4 as compared to the cost, which is $7.
