A dressmaker needs to cut 18-inch pieces of ribbon from rolls of ribbon that are 3 feet in length. How many 18-inch pieces can the dressmaker cut from 15 of these rolls of ribbon?

1. how many inches in total? if each roll is 3 feet in length and considering that there are 12 inches per foot, she has 36 inches of ribbon initially.

(if the question is asking about how many inches she has in the 15 rolls, she would have 45 feet in length which would amount to 540 inches.)

2. How many from 15? In 15 rolls of ribbon, there would be a total of 540 inches of ribbon, so by dividing that by 18 inches (the size of each cut)  she will be able to cut out exactly 30 pieces.

y = x + 95

y = 42 + 95

y=137 mm hg
