A persons weekly wage is worked out by using the formula

Wage=Number of hours overtime times £16 add basic pay

A) Find a persons wage when the number of hours overtime is 9 and the basic pay is £140

B) Find the number of hours of over time, when the wage is £300 and the basic pay is £124

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
