Answer:
a) 378 foot
b) 3780¢
c)
Step-by-step explanation:
Given: Ribbon required to make 1 bow = 1.5 yards
We know that 1 yard = 3 foot
a) Number of bows Jeanne wants to make = 84
Foot of ribbon required to make 84 bows
= Number of bows Jeanne wants to make × Ribbon required to male 1 bow
= 84 × 1.5 yards
= 126 × 3 foot = 378 foot
Thus, Jeanne requires 378 foot of ribbon to make 84 bows.
b) Cost of ribbon = 10¢ per foot
Total money required to buy ribbon
= Cost of ribbon × Amount of ribbon required in foot
= 10 × 378
= 3780.00¢
c) Number of bows manufacture wants to make = 84 × 1000
= 84,000 bows
Amount of ribbon required to make bows
= 1000 × Amount of ribbon required to make 84 bows
= 1,000 × 378 = 378000 foot
