Question

Michael has two jobs. He earns $9.25 per hour at a pet store and earns $8.90 per hour at a telemarking job. If p represents the number of hours worked at the pet store and t represents the number of as a telemarketer, then which inequality describes the relationship between p and the t that is necessary for Michael to earn at least $100?

Answer 1

9.25 p + 8.90 t ≥ 100 describes the relationship between p and the t for Michael to earn at least $100.

Explanation:

p = Number of hours worked at the pet store

Earning per hour at pet store = $9.25

t = Number of hours worked as a telemarketer

Earning per hour at telemarketing job = $8.90

Now, total amount earned at pet store after working p hours = p x $9.25

and total amount earned at tele job after working t hours = t x $8.90

Now, according to the question

Total money earned at pet store + Total earning at telemarketing job = At least $100

⇒ 9.25 p + 8.90 t ≥ 100

Hence, 9.25 p + 8.90 t ≥ 100 describes the relationship between p and the t .
