At noon, a barista notices she has $20 in her tip jar. If she makes an average of $0.50 from each customer, how much will she ha
RSB [31]

Answer:

She has $20 + $0.50n in her tip jar.

Step-by-step explanation:

Amount in tip jar at noon = $20

Average amount made from each customer = $0.50

Number of additional customers served after noon = n

Therefore, we have:

Additional amount made after noon = Average amount made from each customer * Number of additional customers served after noon = $0.50 * n = $0.50n

Amount in tip jar = Amount in tip jar at noon + Additional amount made after noon = $20 + $0.50n

Therefore, she has $20 + $0.50n in her tip jar.

Answer:

The rate of return is 14%

Step-by-step explanation:

The rate of return can be determined by,

RR = \frac{A_{f} - A_{i}  }{A_{i} } x 100%

where:

RR is the rate of return

A_f} is the final amount = $690 -  $6 = $684

A_{i} is the initial amount = $15 x 40 = $ 600

So that,

RR = \frac{684 - 600}{600} x 100%

     = 0.14 x 100%

     = 14%

Therefore, the rate of return is 14%.
