Jimmy and Irene go shopping for clothes on a Tuesday, where senior citizens get a 10% discount on their purchases. Jimmy picks out 3 shorts from the $15 rack. Irene grabs 5 shirts from the $17 rack. How much money do they give to the cashier? Give me reasons, before answering the question
Jimmy's shorts cost 3 x $15 = $45. Irene's shirts cost 5 x $17 = $85. Total cost for the clothes is $45 + $85 = $130. 10% discount on the clothes is $130 x 10% = $13. They give the cashier $130 - $13 = $117. So the final answer is 117.
