Question

Jonah runs a bakery, and his most popular item is cinnamon raisin bread. He has two options to purchase raisins.

Grocery store: 9 ounces for $3.75
Bulk order: 5 pounds for $15.25
If Jonah buys the raisins in bulk, what is his savings per ounce? (16 ounces = 1 pound.)

Answer 1

Jonah saves $0.2261 per ounce by buying raisins in bulk compared to the grocery store option after calculating the cost per ounce for both and subtracting the bulk cost per ounce from the grocery store cost per ounce.

Step-by-step explanation:

To calculate Jonah's savings per ounce when buying raisins in bulk compared to the grocery store, first determine the cost per ounce for each option and then subtract the bulk order cost per ounce from the grocery store cost per ounce.

Grocery store cost per ounce: $3.75 / 9 ounces = $0.4167 per ounce

Bulk order cost per pound: $15.25 / 5 pounds

Bulk order cost per ounce: ($15.25 / 5) / 16 ounces = $0.1906 per ounce

Savings per ounce: $0.4167 - $0.1906 = $0.2261

Jonah saves $0.2261 per ounce by purchasing the raisins in bulk.
