Mealworms are a healthy food for wild songbirds. Adam buys a 3.5-oz container of mealworms for $8.75. Marco buys a 3.75-oz container of mealworms for $9.75. Which container is the better deal?

• Marco's Container

• Adam's Container

A painter mixes  $2\frac{1}{2}$   pints of yellow paint with 4 pints of red paint to make a certain shade of orange paint. How many pints of yellow paint should be mixed with 10 pints of red paint to make this shade of orange? 

• 6 pints of yellow paint

•  $6\frac{1}{5}$  pints of yellow paint

•  $6\frac{1}{4}$  pints of yellow paint

•  $6\frac{3}{4}$  pints of yellow paint

Use the table above that shows information about squares.

Are the perimeter and the side length of squares proportional? Explain.

• No, the ratios $\frac{perimeter}{side\ length}$ for the squares are equivalent, so they are proportional.

• Yes, the ratios $\frac{perimeter}{side\ length}$ for the squares are equivalent, so they are not proportional.

• No, the ratios $\frac{perimeter}{side\ length}$ for the squares are not equivalent, so they are not proportional.

• Yes, the ratios $\frac{perimeter}{side\ length}$ for the squares are equivalent, so they are proportional.

Write and solve a proportion to find the perimeter of a square when its side length is 12.

• $\frac{ }{1}=\frac{4}{12};\ p\ =48$

• $\frac{4}{1}=\frac{ }{12};\ p\ =48$

• $\frac{4}{1}=\frac{12}{ };\ p=48$

• $\frac{4}{ }=\frac{1}{12};\ p\ =48$

Sally is going on vacation with her family. In 2 hours they travel 90.5 miles. If they travel at the same speed, write an equation that represents how far they will travel, d, in h hours.

• d = $\frac{4}{181}$ h

• d = 45h

• d= $\frac{181}{4}$ h

• d = $\frac{1}{45}$ h

The table shows the weights of bunches of bananas and the price of each bunch. Identify the constant of proportionality. Write an equation to relate weight, w, to the price, p.

• k = 1.26; k = 1.26w

• k =3.8; k = 3.8w

• k = $\frac{20}{9}$ ; k = $\frac{20}{9}$ w

• k = 0.45; k = 0.45w

Does the graph show a proportional relationship? Explain.

• No, straight line but also does go through the origin.

• Yes, Straight line and it does go through the origin.

• No; straight line but it does not go through the origin.

• Yes, the graph is a straight line and does not go through the origin.

Identify which graph shows a proportional relationship?

• 
• 
• 

Which of the following graphs goes through the origin but is not a proportional relationship?

• 
• 
• 
• 

Can the problem be solved by using proportional reasoning?

• Yes

• No
