Explanation:
syd:
15x
ril:
10x
15x+10x+(50)=150
25x=100
x=4
sydney: 60 shirts
riley: 90 (since she worked 5 more hours)
sydney worked 4 hours
riley worked 9 hours
60+90=150
Answer:
s = 72.5
r = 77.5
Make a system of equations:
r = s + 5
r + s = 150
Input r into the second equation:
s + 5 + s = 150
2s + 5 = 150
2s = 145
Put this back into one equation
r = 72.5 + 5
