Cindy and Zoey work at a store. Both girls earn $6.25 per hour
wolverine [178]

Answer:

Step-by-step explanation:

I think this is your full question, right?

<em>Cindy and Zoey work at a store. Both girls earn $6.25 per hour. During a normal week Cindy works 15 hours and  Zoey works 20 hours. The expression 6.25(15) + 6.25(20) can be used to calculate the total amount of money that the  girls earned in one week. Which expression shows another way to calculate the amount of money the girls earn in  one week?  </em>

My answer:

The expression shows another way must be equal to: <em>6.25(15) + 6.25(20)  </em>

<=> 6.25 (15+20)

Because both girls earn the same per hour.
