Jay wants to rent a metal detector. A rental company charges a one-time rental fee of $20 plus $5 per hour to rent a metal detector. Jay has only $60 to spend. What is the maximum amount of time he can rent the metal detector?

8 hours.

Step-by-step explanation:

If you have the 20 as the fee, you'd only have 40 dollars left. If you do 40/ 5 you'd get your answer of 8 hours.

Option B is correct.

Step-by-step explanation:

A salary is a fixed amount that you get at your pay day.

A commission is a type of income earned, based on the sales especially. Its given as a percentage of sales. Like a worker is paid $500 fixed salary plus 5% commission on sales above $1000.

So, such worker's salaries vary as they are based on the sales.

Hence, option B seems correct here.

b. Workers being paid on commission have a salary that varies based on their performance.
