Step-by-step explanation:

First step is to identify what the problem is asking for and what is given.

9 laps in 28 minutes

Searching for number of laps in 1 hour and 15 min.

1 hour + 15 min. = 75 minutes convert to minutes

9 laps / 28 minutes = x laps / 75 minutes create an equation

9/28 = x/75

9*75 = 28x cross multiply

675 = 28x

x = 675/28 = 24.12 simplify

Melanie can run 24 complete laps in 1 hour and 15 minutes.

In-s [12.5K]

Answer:

(b)The original price of the shoes is $60.

Explanation:

Part A

In this situation:

• 15% is the PERCENT

• $9 is the PART

• The original price is the WHOLE.

Part B

If 15% is taken off, the customer will save $9.

This means that 15% of the original price = $9.

Let the original price=p

$\begin{gathered} 15\%\text{ of p=9} \\ \frac{15}{100}p=9 \\ 15p=900 \\ p=\frac{900}{15} \\ p=60 \end{gathered}$

The original price of the shoes is $60.
