Suppose you went to a carnival. the price to get in was $8, and you paid $0.50 to get on each ride. if you went to the carnival and rode 9 rides, how much did you spend? (1 point) $4.50 $17.50 $12.50 $13

$12.50

Step-by-step explanation:

The price to get in was $8, and you paid $0.50 to get on each ride.

8 is the fixed price, 0.50 is the cost per ride

We use equation y=mx+b

Where m is the slope, x be the number of rides

y represents the amount spend and b is the fixed price

So equation becomes y = 0.50x + 8

you went to the carnival and rode 9 rides

Plug in 9 for x  and find out y the amount spend

y = 0.50(9) + 8

y= 4.50 + 8= 12.50

you spend $12.50
