You are ordering a pizza and soda for the big game. A deep dish pizza costs $10.25, and a two-liter of soda is $2.00. For each touchdown that the Eagles score on Sunday, Vinny's Pizza lowers the cost by $1.50. How many touchdowns will the Eagles have to score for your bill to come to $4.75? Explain how to solve for the missing value using an equation.

Question

anonymous · Answer

your total cost before any touchdown is $10.25+2.00=\$12.25$
keep subtracting $1.5$ until you get to $4.75$
if you want to make your math teacher happy, solve 
$$12.25-1.5x=4.75$$ for $x$
