ANSWER
$2550.50
Step-by-step explanation
Jun charges $27.95 per oil change.
He charges $95.50 per tune-up.
He does 40 oil changes and 15 tune-ups each week.
In a week, for oil changes:
27.95 * 40 = $1118
For tune-ups:
95.50 * 15 = $1432.50
Therefore, in total, in a week, he makes:
$1118 + $1432.50 = $2550.50
He makes $2550.50 in a week.
