Question

Eliana knit a total of 328 centimeters of scarf over 8 nights. How many nights will Eliana have to spend knitting in order to knit a total of 1,845 centimeters of scarf? Assume the relationship is directly proportional.

Answer 1

We can write a proportion to help us solve

328 cm 1845 cm

--------------- = ----------------

8 nights x nights

Using cross products

328 * x = 1845 *8

328x =14760

Divide each side by 328

328x/328 = 14760/8

x =45

It will take 45 nights
