The total earnings is: $1850, so we have:

Required

Determine the rate of each

The equations are:

--- (1)

--- (2)

Divide (2) through by 5

--- (3)

Subtract (1) from (3)

Divide through by 2

Substitute 105 for y in (1)

Make x the subject

Substitute 105 for y

Hence:

Mechanic 1: $55 per hour

Mechanic 2: $105 per hour
