Write an equation to model this situation where Tis the number of additional hours she worked in May.
Answer provided by our tutors
let y represent the money Sophie earns per month if she works 5 hours and additional T hours:
y = 500 + 14T
if y = 570 then for T we have
14T + 500 = 570
T = (570 - 500)/14
T = 5 hr
Sophie worked 5 additional hours in May.
