Answer:
To solve this question, we need to multiply the per-ride cost, which is $2, by the number of rides, r. Then, we need to add the cost of admission, which is $10, to the cost of the rides.
The equation for the cost of one admission and r rides is:
Cost = $10 (admission) + $2r (rides)
So, to find the cost for one admission and r rides, we need to plug in the value for r. For example, if r = 2, the cost would be:
Cost = $10 (admission) + $2(2) (rides) = $14
So, the cost for one admission and 2 rides would be $14.
Similarly, if r = 4, the cost would be:
Cost = $10 (admission) + $2(4) (rides) = $22
So, the cost for one admission and 4 rides would be $22.
