Step-by-step explanation:
Let
x-----> the original selling price
we know that
so
-----> equation that represent the situation
solve for x
Divide by 0.80 both sides
59
b^3 is 27
2(27) is 54
54+5 is 59
if u mean (2b)^3 then 2b is 6
6^3 is 216
plus 5 is 221
190.625 ft^2
A = bh = (15.25) * (12.5) = 190.625 ft^2
y-y1=m(x-x1)
y-3=5(x+4)
y-3=5x+20
y-5x+3+20=0
y-5x+23=0
455
