It took Grandma Helen 70 minutes to make a 35-inch-long scarf for Sean. To find out how many minutes it will take her to make a 50-inch-long scarf for Shannon, we can set up a proportion:
35 inches / 70 minutes = 50 inches / x minutes
Cross multiplying, we get:
35x = 70 * 50
35x = 3500
x = 3500 / 35
x = 100
Therefore, it will take Grandma Helen 100 minutes to make a 50-inch-long scarf for Shannon.
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?
? minutes
