1.08

$119.22

Sallie does not have enough money to buy the skateboard.

Step-by-step explanation:

If there is a sale for a 20% discount on the regular selling price of a skateboard which is $137.99. So, the discounted price of the skateboard will be given by  

$137.99( 1 - \frac{20}{100}) = 137.99 \times 0.8 = 110.392$

So, the discounted sale price of the skateboard without tax can be found by multiplying the regular price by 0.8. (Answer)

Now, the total cost for the skateboard with sales tax can be found by multiplying the discounted sale price by $(1 + \frac{8}{100}) = 1.08$ (Answer)

{Since, the sale tax is 8%}

Therefore, the total cost for the skateboard will be (110.392 × 1.08) = $119.22 (Answer)

Sallie does not have enough money to buy the skateboard because she has only $115. (Answer)
