Good luck!!!

Answer 2

So, we need to use division to determine the answer.

So, if z is the amount of money we spent today, and it is 5.5 times the amount we spent yesterday. We just need to do inverse operations to find our answer. I will use the variable y for the amount you spent yesterday.

Given: z=5.5y

Divide 5.5 on both sides: z ÷ 5.5 = y

Expression: z/5.5

Answer: z/5.5

Hope I helped!
