Question

Hector spent $36.75 for 2 dvds that cost the same amount.The sales tax was $2.15.Hector also used a coupon for $1.00 of his purchase. How much did each dvd cost.

Answer 1

Each DVD cost for Hector at $17.80.

Explanation:

Total Money Spent = $36.75

Number of DVD to buy = 2

Sales tax = $2.15

Amount of Coupon to be used = $1.00

We need to find the cost of each DVD.

Let the Cost of each DVD be 'x'.

Now We can say that Total Money spent on DVD's is equal to Number of DVD to buy multiplied by Cost of each DVD plus Sales Tax minus Amount Coupon used.

Framing in equation form we get;

`2x+2.15-1=36.75`

Solving the equation to find the value of x we get;

`2x+1.15=36.75\\\\2x=36.75-1.15\\\\2x= 35.6\\\\x=(35.6)/(2)= \$17.8`

Hence Each DVD cost for Hector at $17.80.
