suppose you went to a carnival. the price to get in was $7, and you paid $0.50 to get on each ride. if you went to the carnival and rode 11 rides, how much did you spend?
To calculate the total amount spent, first, calculate the cost of the rides:
$0.50/ride * 11 rides = $<<0.50*11=5.50>>5.50
Then add the cost of admission to find the total amount spent:
$7 + $5.50 = $<<7+5.5=12.50>>12.50
Therefore, you spent $12.50 at the carnival.
