Answer to Problem 33SGR
Matrix for the purchase price:
Explanation of Solution
Given information:
Table for the purchase price and the selling price:
Items | Purchase Price | Selling Price |
shirts | $15 | $35 |
jeans | $25 | $55 |
shoes | $30 | $85 |
From the table,
Purchase price for 1 shirt is $15.
Purchase price for 1 pair of jeans is $25.
Purchase price for 1 pair of shoes is $30.
Thus,
The matrix becomes
(b)

Answer to Problem 33SGR
Matrix for the selling price:
Explanation of Solution
Given information:
Table for the purchase price and the selling price:
Items | Purchase Price | Selling Price |
shirts | $15 | $35 |
jeans | $25 | $55 |
shoes | $30 | $85 |
From the table,
Selling price for 1 shirt is $35.
Selling price for 1 pair of jeans is $55.
Selling price for 1 pair of shoes is $85.
Thus,
The matrix becomes
(c)
To write: Matrix for profit on 1 shirt, 1 pair of jeans, and 1 pair of shoes.
(c)

Answer to Problem 33SGR
Profit Matrix:
Explanation of Solution
Given information:
Table for the purchase price and the selling price:
Items | Purchase Price | Selling Price |
shirts | $15 | $35 |
jeans | $25 | $55 |
shoes | $30 | $85 |
Difference between the selling price and purchase price:
Subtract the corresponding values:
Simplify:
Thus,
The matrix for profit:

- 9:41 … 93 Applying an Exponential Function to Newton's Law of Cooling 60. Water in a water heater is originally Aa ← 122°F. The water heater is shut off and the water cools to the temperature of the surrounding air, which is 60°F. The water cools slowly because of the insulation inside the heater, and the value of k is measured as 0.00351. a. Write a function that models the temperature T (t) (in °F) of the water t hours after the water heater is shut off. b. What is the temperature of the water 12 hr after the heater is shut off? Round to the nearest degree. c. Dominic does not like to shower with water less than 115°F. If Dominic waits 24 hr. will the water still be warm enough for a shower?
