21x -15 + 5 = 10x - 5
21x -5 = 10x
11x = 5
x = 5/11
The answer is B; $ 59.00. All you have to do is multiply the price times 4 and then subtract that from 100. Then do it again and 59 should be your answer.
#11
Each roll is 9' long,
length of each roll = 9' * (12"/foot) = 108"
Each ribbon piece = 15", so number of ribbons per roll
=108/15=7 with 3" left over, which is assumed not possible to be joined with other pieces.
Therefore, with 5 rolls, there are 7*5=35 pieces of ribbon, with 5 pieces or 3" left over.
Yayyyy I’m so happy you got good grades
