How do you calculate a weekly wage from hours worked and an hourly rate?
Show answer
Weekly wage = hours worked × hourly rate. E.g. 34 hours at £15 per hour = £510.
How do you find an hourly rate of pay from total pay and hours worked?
Show answer
Hourly rate = total pay ÷ hours worked. E.g. £469 for 28 hours = £16.75 per hour.
Jacob makes 250 decorations a day at £90 per day. How much does he earn making 3000?
Show answer
£1080 — 3000 ÷ 250 = 12 days, and 12 × £90 = £1080.
A shower costs £309 and a plumber charges £35 per hour for 3 hours. What is the total cost?
Show answer
£414 — £309 + (3 × £35) = £309 + £105.
How do you compare two workers' hourly rates when given total pay and hours for each?
Show answer
Divide each total pay by the hours worked, then compare. E.g. £425 ÷ 25 = £17 versus £342 ÷ 20 = £17.10, so the second rate is higher.
Ben works 42 hours for £453.60 a week. What is his weekly wage after a 65p per hour rise?
Show answer
£480.90 — current rate £453.60 ÷ 42 = £10.80; new rate £11.45 × 42 = £480.90.
What does being paid "double time" for overtime mean?
Show answer
Each overtime hour is paid at twice the normal hourly rate.
Clare earns £11.50 per hour, with double time for overtime. What is she paid for 6 normal hours and 3 overtime hours?
Show answer
£138 — (6 × £11.50) + (3 × £23) = £69 + £69.
What does being paid "time and a half" for overtime mean?
Show answer
Each overtime hour is paid at 1.5 times the normal hourly rate.
Emily earns £12 per hour for the first 36 hours and time and a half after that. What is she paid for 41 hours?
Show answer
£522 — (36 × £12) + (5 × £18) = £432 + £90.
How do you work out overtime hours when given total earnings, normal hours, normal rate and overtime rate?
Show answer
Subtract the normal pay (normal hours × normal rate) from total earnings, then divide the remainder by the overtime rate. E.g. (£651.70 − 32 × £13.80) ÷ £19.10 = 11 overtime hours, so 43 hours in total.
