The length of a deck is 5 less than twice the width with a perimeter of 62 feet. What is
the width of the deck rounded to the nearest tenth?
A. 12.0
B. 12.3
C. 12.8
D. 13.1 Correct Answer A. 12.0
This question is asking you to find the perimeter. Perimeter is the result of ADDING all
the sides of the shape. In this case, we have a rectangular deck. The length is 5 less
than twice the width, which is written 2w-5. And the width is just w.
When you add up all the sides, you get;
2w-5 + 2w-5 + w +w=62
6w - 10 =62
Solve the equation by adding 10 to each side:
6w -10 =62
6w = 72
Divide each side by 6:
w = 12
Left and right side of the rectangle- w
Top and bottom of the rectangle- 2w-5
A car salesperson makes 30% commission from all sales during the month. His base
pay is $240 per month plus what he makes on sales commission. Which of the following
inequalities represents his pay at the end of the month so that he makes no less than

A. .3x + 240 < 640
B. .3x + 240 > 640
C. .3x + 240 <_ 640
D. .3x + 240 >_ 640 Correct Answer D. .3x + 240 >_ 640
