The given equation represents the number of pages pp read, where hh represents the number of hours spent reading.

p=42hp = 42h

Which of the following is the best interpretation of
4242 in this context?

In p=42hp = 42h, the number 4242 is the reading rate: 4242 pages for each hour spent reading.

The given equation represents the weight WW, in ounces, where nn represents the number of identical snack bags.

W=3.2nW = 3.2n

Which of the following is the best interpretation of
3.23.2 in this context?

In W=3.2nW = 3.2n, the number 3.23.2 is the weight in ounces of one snack bag.

The given equation represents the temperature drop TT, in degrees Fahrenheit, where hh represents the number of hours after sunset.

T=2.5hT = 2.5h

Which of the following is the best interpretation of
2.52.5 in this context?

In T=2.5hT = 2.5h, the number 2.52.5 is the drop in temperature, in degrees Fahrenheit, for each hour after sunset.

A bike rental shop charges a flat fee plus an hourly rate. The total cost CC, in dollars, after hh hours is modeled by C=6h+10C = 6h + 10. Which of the following is the best interpretation of 66 in this context?

In C=6h+10C = 6h + 10, the 66 multiplies hours, so 66 is the hourly rental rate in dollars.

A plant's height HH, in centimeters, after ww weeks of growth is modeled by H=1.8w+12H = 1.8w + 12. Which of the following is the best interpretation of 1.81.8 in this context?

In H=1.8w+12H = 1.8w + 12, the 1.81.8 multiplies weeks, so the plant grows 1.81.8 centimeters each week.

Mid-gameeasy

The given equation represents the number of points ss a team has, where gg represents the number of games won.

s=3gs = 3g

Which of the following is the best interpretation of
33 in this context?

In s=3gs = 3g, the number 33 is the points earned for each game won.

The given equation represents the number of seats nn filled, where rr represents the number of rows occupied.

n=18rn = 18r

Which of the following is the best interpretation of
1818 in this context?

In n=18rn = 18r, the number 1818 is the number of seats in each occupied row.

A printer uses ink at a constant rate. The amount of ink left II, in milliliters, after printing pp pages is modeled by I=0.04p+20I = -0.04p + 20. Which of the following is the best interpretation of 0.04-0.04 in this context?

In I=0.04p+20I = -0.04p + 20, the 0.04-0.04 is the change in ink for each page, so 0.040.04 milliliter of ink is used per page printed.
