Answer:

8/30 (Simplified answer: 4/15)

Step-by-step explanation:

Find common denominators. Note the what you do to the denominator, you do to the numerator.

Multiply 10 to both the denominator & numerator of 2/3, and multiply 3 to both the denominator & numerator of 4/10

(10/10)(2/3) - (3/3)(4/10)

Simplify.

(20/30) - (12/30)

Simplify. Combine the terms

(20/30) - (12/30) = (20 - 12)/30 = 8/30

Simplify the fraction

(8/30)/(2/2) = 4/15

Luis wants to buy a skateboard that usually sells for $135. At big AL's they are discounted 20%. What is the total cost of the s
tino4ka555 [31]

Answer:

117.99

Step-by-step explanation:

First step is to find the discount

Discount = original price * discount rate

               = 135 * 20%

                = 135*.20

                 =27

Take the discount from the original price and that is the new price

new price = original price - discount

                 = 135-27

                 =108

Now we need to find the tax

tax = new price * tax rate

       = 108 * 9.25%

       = 108 * .0925

        =9.99

The final price is the new price plus the tax

final price = new price + tax

                 = 108+9.99

                 =117.99
