Math Problem of the Week - Middle School - Sept. 26, 2021 to Oct. 2, 2021

Middle School: 

Question: Dale orders a cup of coffee that costs $1.50 and a slice of cherry pie that costs $2.50 at the Double R Diner. If the sales tax is 6.5% and Dale tips $1.00, then how much money does he spend at the diner in total?

Answer: $5.26

Solution: The cost before tax of the pie and coffee is $1.50 + $2.50 = $4.00, so the cost after tax is $4.00 + ($4.00 x 0.065) = $4.26. With the tip included, Dale spends $4.26 + $1.00 = $5.26
