Question

Mikayla is a waitress who makes a guaranteed $50 per day in addition to tips of 20% of all her weekly customer receipts, t. She works 6 days per week. Which of the following functions best represents the amount of money that Mikayla makes in one week?

A) f(t) = 50 + 20t
B) f(t) = 300 + 20t
C) f(t) = 50 + 0.2t
D) f(t) = 300 + 0.2t

Answer 1

D.
`f(t)=300+0.20t`

Explanation:

We have been given that Mikayla is a waitress who makes a guaranteed $50 per day.

Since Miklaya works 6 days per week, so the guaranteed income for one week would be
`\$50* 6=\$300`

We are also told that she gets tips of 20% of all her weekly customer receipts, t. So amount earned from tips would be 20% of t, that is
`(20)/(100)t=0.20t`.

Total amount earned in one week would be guaranteed income for 1 week plus 20% of t:

`300+0.20t`

Therefore, our required function is
`f(t)=300+0.20t` and option D is the correct choice.
