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?f(t) = 50 + 20tf(t) = 300 + 20tf(t) = 50 + 0.2tf(t) = 300 + 0.2t

Answer 1

Option D:
`f(t)=300+0.2 t`

Explanation:

We are given that Mikayla is a waitress

She makes a guaranteed per day =$50

Her tips per day =20 % of weekly tips t

We have to find a function that represents the amount of money makes by Mikayla in one week

`20% of t=(20)/(100)t=0.2t`

She works per week=6 days

She earns in 6 days=
`50* 6`=$300

Total earning of Mikayla in one week =
`300+0.2t`

`f(t)=300+0.2 t`

Hence, option D is true.

Answer 2

$50 per day x 6 days = 300

20% = 0.2, times t = 0.2t

The equation would be: f(t) = 300 + 0.2t
