The storage container below is in the shape of a rectangular prism with a height of 6 feet and a length that is 2 feet more than its width. Recall that the formula for the volume of a rectangular prism is V = l · w · h, where l is the length, w is the width, and h is the height. Write the equation that represents the volume of the storage container in terms of its width.

Apples cost $1.25 per pound. Oranges cost $1.49 per pound. Krystal wants to buy 3 pounds of apples and some oranges. She has $10.00 to spend. How many pounds of oranges can Krystal buy? A. Make a double bar graph. Graph $1.25 using one color and $1.49 using another color. Then graph the cost of 2 pounds of each fruit, then graph the cost of 3 pounds of each fruit. Keep graphing until one of the costs is more than $10. B. Make a table. Write 1, 2, 3, 4, 5, 6, 7, 8 (the number of pound of oranges) on the top row and write the total cost of the apples ($1.25 × 3) in every box on the second row. Fill out the cost of 1, 2, 3, 4, 5, 6, 7, 8 pounds of oranges on the third row and the total cost on the bottom row. The correct answer is the number of pounds of oranges that can be purchased that makes the total cost closet to $10, but not more than $10. C. Draw a diagram. Draw 10 boxes to represent the $10 Krystal has. Draw an apple in 3 of the boxes to show the 3 pounds of apples Krystal will buy. Count the number of empty boxes to determine the number of pounds of oranges Krystal can buy.
