A landscape can buy sod at a discounted price from the local hardware store. If she can buy a length of sod on sale for $7, what is the original price of the sod if he pay 50% off original price

Step-by-step explanation:

Step one:

given data

we are told that the discounted price is $7

and the applied discount is 50%

so if 50% of the original price is $7

Step two:

let the original price be x

50/100*x=7

0.5x=7

divide both sides by 0.5

x=7/0.5

x=$14

These means that the original price is $14

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
