Proportionality Review

Anika, Abigail, and Michael are having a breakfast party! They found a box of cereal that weighs 14 ounces and costs $2.66. They are curious to know, what is the price per ounce of the cereal they are munching on?

• $0.19

• $0.25

• $0.30

• $0.12

Answer explanation

To find the price per ounce of the cereal, we need to divide the total cost of the cereal ($2.66) by the total weight of the cereal (14 ounces). This calculation gives us $2.66 / 14 = $0.19 per ounce, which is the correct answer.
