Armando and drew do volunteer work at an animal shelter. Drew worked 3 more hours than armando, and together they worked more than 27 hours. What is the least number of hours each worked?:confused: :confused: :eek:

Lets have Drew = x
and Armando = y

y=x+3
x+y>27

x+(x+3)=27

2x+3=27
2x=24
x=12

12+y=27
y=15

The least amount they worked was

x>12
y>15

because they worked more than 27 hours so it has to be greater than a total of 27
