Question

A factory worker does decorative stitching on
jeans. He stitched 37 pairs of jeans from 8:00
a.m. to 12:00 noon.
If he took a 45-minute break during that
time, which equation can be used to determine
j, the average number of pairs of jeans he
completed per hour of work?

Answer 1

a. j = 37 ÷ (4 − 0.75)
b. j = (37 − 0.75) × 4
c. j = (37 − 0.75) ÷ 4
d. j = 37 × (4 + 0.75)
e. j = 37 × (4 − 0.75)

Answer 2

he stitched 37 pair of jeans in 4 hrs
he took 45 minute break....which is 75% of an hr, which is 0.75

so : j = 37 divided by (4 - 0.75)

Answer 3

Thank you for explaining what the .75 meant i was kind of confused about that
