The commission Richard Klein earns for oil change = 3.00%
The commission he earns for tune ups = 5.00%
The commission he earns for auto parts sales = 6.25%
The minimum salary he is guaranteed = $2,450.00
The amount he brought in last month includes;
1) $2,500.00 in oil changes
2) $4,500 in tune ups
3) Sold $28,200.00 in parts
The amount he earns last month in commission are;
3/100 × 2,500 = 75 in oil changes
5/100 × 4,500 = 225 in tune ups
6.25/100 × 28,200 = 1762.5 in parts sold
The total commission = 72 + 225 + 1762.5 = 2,059.5
∴ The total commission = $2,059.5
The amount he makes as salary = $2,450.00
Richard Klein's gross pay for the month = His total pay for the month
Therefore;
Richard Klein's gross pay for the month = $2,059.5 + $2,450 = $4,509.5
