I would do it this way
$780+$225=$1005
$1005/120ft= $8.375
if you have to round up $8.38 per foot
I believe you would have to multiply both 25 and 20 and what ever number you get dived by 100 if the numbers to high multiply aging or subtract the number (if it's wrong I'm really not good at my math I'm sorry)
Answer:
Step-by-step explanation:
Area of rectangle = length * width
= (x + 4) (5x)
= x *5x + 4 *5x
= 5x² + 20x
Perimeter of rectangle = 2*(length + width)
= 2*(x + 4 + 5x)
= 2*(6x + 4)
= 2*6x + 2 *4
= 12x + 8
Answer:
= 7.5x-8
Step-by-step explanation:
Total cost = cost per yard * yard of fabric - coupon
total cost = 7.5 x - 8
y = 7.5x-8
Answer:
y=-5x+12
Step-by-step explanation:
just use a graphing calculator and basic knowledge of slope intercept form
