Christian's curtain company is making curtains for a local hotel. He wants each curtain to be 24 inches long. At the fabric store, fabric is sold by the foot. If Christian's curtain company wants to make 79 curtains, how many feet of fabric will he need?

Step-by-step explanation:

Using the conversion

1 foot = 12inches

Convert 24 inches to feet

1 foot = 12inches

x foot = 24inches

cross multiply

12 * x  = 24

12x = 24

x = 24/12

x = 2 feet

Hence 24inches = 2 feet

This means that a curtain is 2feet long

If the Christian's curtain company wants to make 79 curtains, the dimension of 79 curtains in feet will be:

2 * 79 = 158 feet

Hence 158feet of fabric will be used

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
