Question

Farah found 7 rolls of teal ribbon and blue ribbon. Each roll of teal ribbon was 1 meter long and each roll of blue ribbon was 7 meters long. If Farah found 37 meters of ribbon in total, how many rolls of each color did she find?

Answer 1

Blue: 5 rolls

Teal: 2 rolls

Explanation:

1 x T + 7 x B = 37

T + B = 7

(7 - B) + 7B = 37

7 + 6B = 37

6B = 37 - 7 = 30

B = 5

T = 2
