Brian should purchase Choice C of fabric

Solution:

Given that Brian wants to purchase a piece of fabric  that is between 49 and 53 inches long

So piece of fabric should be between: 49 and 53 inches

Let us convert feet to inches

Now convert to inches

We know that,

1 feet = 12 inches

But this choice is greater than given condition that piece of fabric should be between: 49 and 53 inches

So this is not correct

Now convert to inches

But this choice is greater than given condition that piece of fabric should be between: 49 and 53 inches

So this is not correct

Now convert to inches

So this 52 inches lies between 49 and 53 inches

So Brian should purchase Choice C of fabric

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
