Question

Sarah visits an amusement park with an admissions cost of $24. Each ride costs $3. She does not buy any food or drink while she is there. If y represents the total she spends at the park and she takes x rides, which of the following is a function that represents her total spending? 

A. y=24x+3

B. x+y=27

C. y=3x+24

D. y=27x

​

Answer 1

Option C. y=3x+24 is the correct answer

Explanation:

Using the given information,

Number of rides = x

Total cost = y

Admission cost = $24

The admission cost is a one-time cost that will remain constant while each ride costs 3 dollar so for x rides the cost will be 3x.

The total cost, if she buys no food or drink will be: 24+3x

Now we know that total cost is equal to y then

y = 24+3x

OR

y = 3x+24

Hence,

Option C. y=3x+24 is the correct answer
