Two in-line skaters, Nell and Kristin, start from the same point and skate in the same direction. Nell skates at 16 miles per ho

Paha777 [63]

First, we count how far reached the Nell:
3,5 * 16 = 56 miles

Secondly, we count how far reached the Kristin:
3,5 * 18 = 63 miles

Now we expect the difference in the distance between them:
63 - 56 = 7 miles

The results that Kristin about seven miles driven more than Nell.

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify given.</em>

<em /> $\displaystyle f(x) = 3.55x - 4$

$\displaystyle x = \{ 17, 21, 24, 34 \}$

<u>Step 2: Find Profit</u>

To find the <em>profit</em> the store makes each day, we <em>input</em> the number of customers that visited the store each day into our given function:

For the day that had 17 customers:

$\displaystyle\begin{aligned}f(17) & = 3.55(17) - 4 \\& = 60.35 - 4 \\& = \boxed{56.35} \\\end{aligned}$

∴ the butcher store made $56.35 when <em>17 customers</em> visited the store.

For the day that had 21 customers:

$\displaystyle\begin{aligned}f(21) & = 3.55(21) - 4 \\& = 74.55 - 4 \\& = \boxed{70.55} \\\end{aligned}$

∴ the butcher store made $70.55 when <em>21 customers</em> visited the store.

For the day that had 24 customers:

$\displaystyle\begin{aligned}f(24) & = 3.55(24) - 4 \\& = 85.2 - 4 \\& = \boxed{81.2} \\\end{aligned}$

∴ the butcher store made $81.20 when <em>24 customers</em> visited the store.

For the day that had 34 customers:

$\displaystyle\begin{aligned}f(34) & = 3.55(34) - 4 \\& = 120.7 - 4 \\& = \boxed{116.7} \\\end{aligned}$

∴ the butcher store made $116.70 when <em>34 customers</em> visited the store.
