I think 517.26
I did 10 times 3^2 (9) it equals 90. Then 90 times 3.14 and got 282.74. Then did 800- 282.74 and got 517.26
Answer:
$22.50
Step-by-step explanation:
I think the unit of the sand sold is actually in cubic inches and not square inches.
V = L*B*H
V = 2.5 * 3 * 6
V = 45 in³
If 1 in³ = $0.50
45 = x
x = 45 * $0.50
x = $22.50
Y= 3.11x+ 17.59
I got this equation by doing 23.81-20.70 to find m, which is 3.11.
Then to find b, or y-intercept, I subtracted 3.11 from 20.70 to get the origin all price and got 17.59
