Question

A coffee seller makes a salary of 3,500 dollars per month plus $12 commission for every $100 of coffee he sells. a case of coffee costs $25. How many cases of coffee did he sell if his pay at the end of the month is $3,650?

Answer 1

50

Explanation:

The total salary was $3650.

The base salary is $3500.

$3650 - $3500 = $150

He made $150 in commission.

He makes $12 commission for every $100 he sells.

$150/$12 = 12.5

He sold 12.5 amounts of $100.

Each $100 corresponds to 4 cases.

12.5 × 4 = 50

He sold 50 cases of coffee.
