Question

Sofia needs 8 inches of ribbon to make 1 party favor. Which of the following lengths would be enough ribbon for Sofia to make from 15 to 20 party favors? 1 inch 5 2.54 centimeters, 1 centimeter < 0.39 inch

A 61 centimeters
B 390 centimeters
C 405 centimeters
D 411 centimeters
E 490 centimeters

Answer 1

D: 411 centimeters

Explanation:

1. Multiply 8 by 15 you'll get 120 inches from this
2. Multiply that by 2.54 to find how many centimeters it is. It would be 304.8 centimeters.
3. Then repeat steps 1-2 but replace 15 inches with 20 inches. When you multiply it by 8 it becomes 160 and it becomes 406.4 centimeters when it's multiplied by 2.54 which is why the correct answer is D

Answer 2

First, we need to determine how much ribbon Sofia needs for each party favor. Since she needs 8 inches of ribbon for one party favor, we can convert that to centimeters (since the answer choices are given in centimeters):

8 inches x 2.54 cm/inch = 20.32 cm

So Sofia needs 20.32 cm of ribbon for each party favor.

To find out how much ribbon she needs for 15 to 20 party favors, we can multiply the amount needed for one party favor (20.32 cm) by the number of party favors:

15 party favors x 20.32 cm/party favor = 304.8 cm
20 party favors x 20.32 cm/party favor = 406.4 cm

The closest answer choice to this range is C, 405 centimeters. Therefore, C is the correct answer.
