Question

The original price of an item, x dollars, is discounted by 15%. A coupon for $2.00 off is applied to the discounted price. Given that x is more than $10.00, which of the following functions gives the final price of the item for the given value of x?

A. F(x)=0.15x-2.00

B. G(x) =0.15x+2.00

C. H(x)=0.85x-2.00

D. T(x)=0.85x+2.00

E. R(x)=-0.85x+2.00

Answer 1

H(x) = 0.85x -2.00

Explanation:

The original price of an item, x dollars, is discounted by 15%.

Let x be the original price of an item

15% =0.15 discount , so discounted amount is 0.15x

Now we subtract discounted amount from original amount

x - 0.15x = 0.85x

A coupon for $2.00 off is applied to the discounted price.

$2.00 is off, so we subtract 2

Function becomes H(x) = 0.85x -2.00
