Question

Alexis and Becca volunteer work at Adopt-a-Pet Animal Shelter. Alexis worked 15 hours less than Becca. Given that they worked a total of 85 hours at the shelter last summer. How many hours did Becca work?

Answer 1

Answer:50 hours

Explanation:

x=Becca´s work hours

(x-15)=Alexis´s work hours

x+(x-15)=85

2x-15=85

+ 15 +15

2x=100

2/2x=100/2

x=50hrs

Check:

x+(x-15)=85

50+(50-15)=85

100-15=85

True.
