Answer:
job would pay $200 and be 10 hours long.
Explanation:
solution
we consider here number of hours the servant work = x
so here equation for amount Nick spends
10 x + 100 ...............1
and
next job pay amount is
15 x + 50 .....................2
now we equate both equation and we will get x
10 x + 100 = 15 x + 50
solve it we get
x = 10
put in equation 2 we get
= 15 (10) + 50 = 150 + 50 = 200
so here job would pay $200 and be 10 hours long.
