Given:
The school has 4 large bulletin boards that each need 9 yards of border.
So, the number of borders = 4 x 9 = 36 yards
There is also a small bulletin board that only needs 12 feet of border.
So, the total borders = 36 yards and 12 feet
Convert from yard to foot
1 yard = 3 feet
So, 36 yards = 36 x 3 = 108 feet
So, the total borders in feet = 108 + 12 = 120 feet
The border is sold in 40- foot rolls
So, the number of rolls =
So, the answer will be:
The number of rolls will the teachers use = 3 rolls
