Answer:

10 hrs

Explanation:

sally earns $5/hr while Adam earns $4/hr

let the number of Hour sally works be 'x'

From question Adam work 2 hrs more than sally,

therefore Adam works (x + 2)hrs also the both earn same amount per week

therefore;

4 x
(x + 2) = 5 x
x

4x + 8 = 5x

5x - 4x = 8

x = 8hrs

Adam works for (8+2)hrs = 10hrs
