Answer:
Clayton = $16.56
Danielle = $9.36
Step-by-step explanation:
from this we can form an equation using two data points
Using (125, 7.50) and (150, 9)
put in the formula (y-y1)/(x-x1) = (y2-y1)/(x2-x1)
x1 = 125, x2 = 150 , y1 = 7.5-, y2 = 9
(y - 7.5)/(x- 125) = (9-7.50)/(150-125)
(y - 7.5)/(x- 125) = 1.5/25= 0.06
y = 0.06(x-125) + 7.5
y = 0.06 x - 7.5 + 7.5
y = 0.06x
we can use the equation to solve both questions
Clayton needs 23 ft = 276 inches
y = 0.06(276) = $16.56
Danielle needs 12ft = 156
y = 0.06(156) = $9.36
