Group like terms then
add like terms

d-2d-10+7=8-10+d
-d-3=-2+d
add d to both sides
-3=-2+2d
add 2 to both sides
-1=2d
divide both sides by 2

Verdich [7]

we know that

The area of a rectangle is equal to

A=L*W

where

L is the length of the rectangle

W is the width of the rectangle

Step 1

<u>Find the area of Mr. Nunez's lawn</u>

in this problem we have

L=50 ft

W=35 ft

so

A=50*35=1,750 ft^2

Step 2

<u>Find the cost of the lawn service charge per square foot</u>

Divide the total paid by the area

\frac{350}{1,750} \frac{\$}{ft^{2}} =0.2\frac{\$}{ft^{2}}

therefore

<u>the answer is</u>

0.2\frac{\$}{ft^{2}}
