Question

In the winter, Grandma Helen knits scarves for her family members. It took her 70 minutes to make a 35-inch-long scarf for her grandson, Sean. Now, she wants to make a 50-inch-long scarf for her granddaughter, Shannon. If Grandma Helen knits at the same rate, how many minutes will it take her to make Shannon's scarf?

Answer 1

Answer:

100 minutes

Step-by-step explanation:

Set up a proportion where x is the amount of minutes it will take her to make the 50 inch long scarf:

$\frac{70}{35}$ = $\frac{x}{50}$

Cross multiply and solve for x:

35x = 3500

x = 100

So, it will take her 100 minutes to make Shannon's scarf
