Question

Tanya spent $8.15 on 5 cans of tuna. She used a coupon that gave her 35¢ off each can. What was the price of a can of tuna without the coupon? Enter your answer in the box. $

Answer 1

Price per can:  x.  Then:  $8.15 = 5(x-$0.35).  Then $8.15=5x -$1.75.
Finally, $8.15+$1.75 = 5x, and x = $1.98.

Check:  The sale price per can is $1.98, less $0.35, or $1.63.  Does 5 times $1.63 come to $8.15?  YES
