Answer to Problem 20PPE
The three different expressions for shorts and tops are
Explanation of Solution
Given:
The prices of clothing are mentioned below in Table 1.
Shorts | Polos | T-shirts |
$16.99 | $17.99 | $15.99 |
$14.99 | $13.99 | $11.99 |
Table 1
Calculation:
Consider the first situation if the person wants to buy 8 shorts at $16.99 and 4 tops at $17.99 and 4 at $13.99.
The expression for the first situation is
Consider the second situation if the person wants to buy 4 shorts at $16.99, 4 shorts at $14.99 and 4 tops at $17.99 and 4 at $13.99.
The expression for the first situation is
that can be calculated as follows:
Consider the third situation if the person wants to buy 4 shorts at $16.99, 4 shorts at $14.99 and 8 tops at $17.99.
The expression for the first situation is
that can be calculated as follows:
Conclusion:
Thus, the three different expressions for shorts and tops are
(c)
To find: The largest and smallest amount of money can be spent on the 8 shorts and 8 tops if
(c)
Answer to Problem 20PPE
The greatest amount to pay is
Explanation of Solution
Calculation:
The largest amount of money can be spent on 8 shorts and 8 tops if the person buys the most expensive shorts and tops.

Calculate the price for 8 shorts and 8 tops.
Now apply
Now find the actual amount that has to pay to seller.
The smallest amount of money can be spent on 8 shorts and 8 tops if the person buys the cheapest shorts and tops.
Calculate the price for 8 shorts and 8 tops.
Now apply
Now find the actual amount that has to pay to seller.
Therefore, the greatest amount to pay is
Conclusion:
Thus, the greatest amount to pay is
