First, you need to create an equation for this problem. Remember 14% = 0.14
($6,050 × 0.14 + $6,050) + $150
Now, all you would have to do is solve it. You would start in the parenthesis using the order of operations (PEMDAS).
($6,050 × 0.14 + $6,050) + $150
$6,897 + $150 = $7,047
His total pay last week was $7,047.
I hope this helps!
