Step-by-step solution for: Unit Rate Worksheets
Let's solve each problem step by step and determine the better buy by comparing unit prices (price per unit of measurement, like per ounce or per item).

> Chloe is buying mixed nuts at a grocery store. She can either spend $7.95 on a 13.21 ounce bag or $7.78 on a 24-ounce bag. Which is a better buy? Show your reasoning.
Step 1: Find the unit price for each option.
- Option A: $7.95 for 13.21 ounces
Unit price = $7.95 ÷ 13.21 ≈ $0.6018 per ounce
- Option B: $7.78 for 24 ounces
Unit price = $7.78 ÷ 24 ≈ $0.3242 per ounce
Comparison:
$0.3242 < $0.6018 → Option B is cheaper per ounce.
✔ Better buy: The 24-ounce bag for $7.78.

> Joseph is shopping for school supplies. He can buy a box of 24 pens for $4.32 or a box of 36 pens for $6.45. Which is a better buy? Show your reasoning.
Step 1: Find unit price per pen.
- Option A: $4.32 ÷ 24 = $0.18 per pen
- Option B: $6.45 ÷ 36 ≈ $0.1792 per pen
Comparison:
$0.1792 < $0.18 → Option B is slightly cheaper per pen.
✔ Better buy: The box of 36 pens for $6.45.

- Option B: $4.60 ÷ 4 = $1.15 per tube

$1.15 < $1.30 → Option B is cheaper per tube.

> Trent and his dad are arguing about toilet paper. Trent thinks that 4 rolls for $9.84 is a better buy than 20 rolls for $13.80. Which is a better buy? Show your reasoning.
Step 1: Find unit price per roll.
- Option A (Trent’s choice): $9.84 ÷ 4 = $2.46 per roll
- Option B: $13.80 ÷ 20 = $0.69 per roll
Comparison:
$0.69 < $2.46 → Option B is much cheaper per roll.
