Answer 1

Answer:

$12

A 34572 B

Step-by-step explanation:

Create a linear equation for contractor A:

slope = $\dfrac{227292-129952}{1833-1048}=124$

$\implies y-129952=124(x-1048)\\\\\implies y=124x$

Difference in price per square foot = 124 - 112 = $12

The next part of the question depends on the size of the house in square footage.

If we take the house to be the sum of the square feet shown in the table for Contractor A, then total square footage = 1048 + 1833 = 2881

So Contractor A costs 2881 x 12 = 34572 more than Contractor B

Answer 2

For contracter B

• y=112x

Compare to y=mx+b

• m=slope=112

For contracter A

$\\ \rm\Rrightarrow m=\dfrac{227292-129952}{1833-1048}$

$\\ \rm\Rrightarrow m=124$

So

Difference=124-112=12
