Jena had $45 to spend at the fair. If the admission to the fair is 2.50 and the ride cost $3 each, what is the greatest number of rides Jena can go on?

Greatest number of ride she can go = 14

Step-by-step explanation:

Jena has $45 to spend at the fair. The admission amount is $2.50 and the ride cost $3 each. The greatest number of rides Jena can go can be computed as follows

Let

a = number of ride

The total cost for the fair = 2.50 + 3a

The amount she has to spend which is her total cost is 45 dollars. Therefore,

total cost = $45

45 = 2.50 + 3a

45 - 2.50 = 3a

42.5 = 3a

divide both sides by 3

a = 42.5/3

a = 14.1666666667

a ≈ 14.17

Greatest number of ride she can go = 14
