Dave buys a base ball for $15 plus an 8% tax. mel buys a football for $20 plus an 8% tax. what is the difference,in dollars of the amount save and mel pay

To find the total amount Dave and Mel paid, apply the taxes to their initial purchases.

Dave paid $15 for a baseball. There was an 8% tax added to this total afterwards. To add the tax to the amount Dave paid, convert the percentage into a decimal:



Multiply the cost of the baseball by this decimal to find the tax:



Add the tax onto the cost:



Dave paid $16.20 in total for the baseball.

Mel paid $20 for a football. There is an 8% tax added to this total afterwards. We already have the decimal for an 8% tax, so we can multiply the football's cost by the decimal:



Add the tax onto the cost:



Mel paid $21.60 for the football.

Subtract the bigger cost by the smaller cost:



There is a $5.40 difference between Dave's and Mel's purchases.
