A persons weekly wage is worked out by using the formula

LuckyWell [14K]

The formula is : #of overtime hours(h) *£16 + basic pay (b)
So, the easier way to put it is W=h*16+b

A: Wage= £284

A. W=h(9)*16+b(140)
=9*16+140
=144+140
=284

B: Overtime = 11
So, with this one, we work backwards
Using the same formula

W=h*16+b
We can fill in
300=16h+124

First, subtract 124 on both sides leaving

176=16h
Now we divide 16 on both sides, canceling out the right side
Leaving
11=h
