777dan777 [17]

Answer:

In total you can buy 3 snacks and ride 4 rides.

Step-by-step explanation:

$2 per ride

$5 for snacks

The equation here is $2r + $5s = $23

First I found out how many times I could multiply 5. First I though 4 but 2 doesnt go into the remaining 3, so I lowered it down to 15 which is 3.

So s = 3

Now our equation is 2r + 15 = 23

Subtract 23 - 15 = 8

Now divide

r = 8 / 2

r = 4
