Answer:
$0.50
Step-by-step explanation:
Suppose that a person bought six T-bone steaks that cost $15.99 per pound
The weight that is listed on the package is 5.77 pounds.
The scale that weighed the package is accurate to within 1/32 pound
Let assume x is the range of the weight listed on the package,
Then:
[tex]|x-5.77| \leq \dfrac{1}{32} \ --- \ (1)[/tex]
Using the method of absolute value inequality;
[tex]- \dfrac{1}{32} \leq x -5.77 \leq \dfrac{1}{32}[/tex]
[tex]5.77- \dfrac{1}{32} \leq x \leq \dfrac{1}{32}+ 5.77[/tex]
[tex]5.77- 0.03125\leq x \leq 0.03125+ 5.77[/tex]
[tex]5.73875 \leq x \leq 5.80125[/tex]
The amount per kilogram undercharged or overcharged is :
[tex]=\dfrac{1}{32} \times 15.99[/tex]
= $0.50
