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
where x is the amount of minutes it will take her to make the 50 inch long scarf: 70 over 35 = x over 50. now u cross multiply and solve for x: 35x= 3500 x = 100 it will take her 100 minutes to make that scarf
