Edwin uses 4 rolls of green ribbon and 8 rolls of purple of ribbon for a project each roll of green ribbon has a length of 90 feet each roll of purple ribbon has a length of 60 feet what is the difference in length in feet between the total amount .org green ribbon and the total amount of purple ribbon edwins uses

120 feet

Step-by-step explanation:

Given

No.of green ribbon rolls used=4

No.of purple ribbon rolls used=8

Length of ribbon in one green roll=90 feet

Length of ribbon in one purple roll=60 feet

In order to find the difference in total green and purple ribbon used, we have to calculate the total length of the ribbons used.

Total length of green ribbon=Number of rolls*length of ribbon in one roll

=4*90

=360 feet

Total length of purple ribbon=number of rolls*length of ribbon in one roll

=8*60

=480 feet

The difference between the total length of green ribbon and purple ribbon=480-360

=120 feet  ..
