A business discovers a linear relationship between the number of shirts it can sell and the price per shirt. If the shirts cost

Setler [38]

It makes sense to let the # of shirts sold be the variable dependent upon the unit cost per shirt.

Notice that the # sold declines as the price increases.

Thus, the slope of this line will be -.

8000 - 5000 3000 shirts
m = ------------------- = ----------------- = -200 shirts per dollar price increase
25 - 40 -15

Using this table below, what is the rate of change? Don't forget to include your units.

NeX [460]

(24,18)(28,21)
slope(rate of change) = (21 - 18) / (28 - 24) = 3/4 <==

The 7th grade class experienced a 15% decrease in enrollment. Last year, the 7th grade class had 280 students. How many students

Monica [59]

238 students are enrolled in the 7th grade class this year

<u>Solution: </u>

Given that

Percentage decrease in number of students enrolled in 7th grade = 15%

Number of students enrolled last year = 280

Need to determine number of students enrolled in 7th grade this year.

Lets assume number of students enrolled this year = x

<em>Percentage decrease in enrollment </em>= (Number of student enrolled last year – Number of students enrolled this year) whole divided by number of students enrolled last year multiplied by 100

$\begin{array}{l}{\Rightarrow 15=\frac{280-x}{280} \times 100} \\\\ {=>15 \times 280=28000-100 x} \\\\ {=>100 \mathrm{x}=28000-4200=23800} \\\\ {\Rightarrow x=\frac{23800}{100}} \\\\ {\Rightarrow x=238}\end{array}$

Hence number of students enrolled this year = 238.
