Question

Cameron is going to the state fair. The price of admission to the fair is $4, and each ride costs an additional $1. If he can spend at most $20 at the fair, which inequality gives the maximum number of rides, r, for Cameron?

Answer 1

So, We start by charging 4 dollars, then 1 dollar per ride.

Let's call r our number of rides.

So

`4+1r\leq20\\4+r\leq20\\r\leq16`

Cameron can ride 16 rides at most

Answer 2

To find the answer, we need to first find the amount he can spend on the rides, by deducting the admission price from the total amount he has got:

20-4

=$16

As he has $16 and each ride cost $1, the maximum rides he can take is:

16÷1

=1

To represent that the maximum rides is 16, we can use the less than or equal to, and therefore the answer is:

r ≤ 16

Hope it helps!
