Question

After receiving a pay rise of 4.5%, Becky's rate of pay increased to $18.81 per hour.

a) What was her pay before the increase?

b) How much extra will she earn over a full year if she works 35 hours each week?

Answer 1

p = old pay

p + 4.5%(p) = new pay

 

p + 0.45p = 18.81

1.045p = 18. 81

p = 18.00

 

Now you can answer b)!
