Answer:
3 hours
Explanation:
let us first model the amount that Jaime and Jon will charge
let the total amount be y and let the number of hours be x
Jaime will charge
y=30+4x------1
Jone will charge
y=50x-----2
equating 1 and 2 we can solve for x which is the number of months Jaime and Jon will charge the same price
50x=30+40x
50x-40x=30
10x=30
divide both sides by 10 we have
x=30/10
x=3
