Help with part A and part B

Vitek1552 [10]

A. You can use y=mx+b to find the rate of change of a bushel corn in the current year. The rate of change would be y=8x.

B. One bushel is worth 8$ (24/3 = 8) in the current year, and in the previous year one bushel was worth 7$ (21/3= 7). Therefore there was a 1$ raise from the previous year to the current year.

A contractor is hired to build an apartment complex. Each 840-square-foot unit has a bedroom, kitchen, and bathroom. The bedroom

Dennis_Churaev [7]

Answer:

350 sq ft

Step-by-step explanation:

Given that:

840 sq ft area has a bedroom, kitchen and bathroom.

Let the area of bedroom be $x$ sq ft.

Then the area of kitchen will also be $x$ sq ft.

Let the area of bathroom be $y$ sq ft.

As per question statement:

$x+y+x=840\\\Rightarrow 2x+y=840 ...... (1)$

Tiles ordered to cover two kitchens and two bathrooms is 980 sq ft.

i.e.

$2x+2y=980 ..... (2)$

Subtracting equation (1) from (2):

i.e. (2) - (1):

$y = 140$ sq ft

Putting the value of $y$ in (1):

$2x+140=840\\\Rightarrow 2x =700\\\Rightarrow \bold{x=350\ sq\ ft}$

Therefore, the carpet needed for each bedroom = <em>350 sq ft</em>
