Answer:
Derrick mistakenly combined the numbers adding it together but the numbers are not the same value to be combined. You cannot add yards and ft together.
Width = 55ft
Area = 4950 sq ft
Cost = $9900
Step-by-step explanation:
Derrick mistakenly combined the numbers adding it together but the numbers are not the same value to be combined. You cannot add yards and ft together.
You have to convert the yards to ft to add it to the other ft.
1 Yard = 3 ft
So the width is 18 yards 1 ft = 54ft + 1ft = 55ft
To calculate the area is L x W
The length is 30 yards. Convert that to ft = 90ft
So 90 x 55 = 4950 sq ft
At $2 per sq ft, you multiply the 4950 sq ft by $2
2 x 4950 = $9900

Answer:
(y1-y2)/(x1-x2)
Step-by-step explanation:
if you have two points from the graph then you can use them to find the slope, for example:
(2,3) and (0,5)
you would take the first point and put it in a fraction (and the second point) but the x goes on the bottom and the y goes on the top:
3/2 and 5/0
Next you put them together minusing one of the equations, but make sure that the two coordinates line up (it doesn't matter which one, in the order):
3-5/2-0
Then you solve:
-2/2
-1
which means that -1 is the slope for this
(the "/" is a fraction bar, in case you didn't already know that)
Use the given information to write an equation, then solve it.
$1600 = (1 + 1 + 1/2)×(monthly rent) . . . . relationship given in the problem statement
$1600/2.5 = monthly rent = $640 . . . . divide by the coefficient of monthly rent
