Christopher earned 153.20. he saved 34.50. he spend the rest on 2 new pairs of shoes. how much did christopher spend on his new shoes ?

Christopher spent $59.35 on his 2 brand new shoes.

Step-by-step explanation:

Christopher has 153.20. He saved 34.50. So that means he saved the 34.5 out of the 153.2.  So to find the sum that he spent you subtract.

153.20-34.50=118.70

So he has 118.70 to spend. He spend the rest on two shoes. If the money is gone you simply divide by two and have you're answer.

118.70/2=59.35

Hope it helps!
