Final answer:
The options with a unit price of $4.25 are 4 books for $17.00 and 5 boxes of cereal for $21.25.
Step-by-step explanation:
To find the unit price, we divide the total price by the quantity. Let's calculate the unit price for each option:
- 2 burritos for $9.50: $9.50 / 2 = $4.75
- 4 tacos for $9.00: $9.00 / 4 = $2.25
- 4 books for $17.00: $17.00 / 4 = $4.25
- 5 boxes of cereal for $21.25: $21.25 / 5 = $4.25
- 10 hamburgers for $45.00: $45.00 / 10 = $4.50
Based on the calculations, options C) 4 books for $17.00 and D) 5 boxes of cereal for $21.25 have a unit price of $4.25.
