Finger [1]

Answer:

  D.  $66.23

Step-by-step explanation:

The sale discounts your purchase by half the price of a pair of pants, so you pay for 2.5 pairs of pants. The sale price of the pants is then ...

  $24.99 × 2.5 = $62.48

The added tax multiplies this value by 1.06, so you pay ...

  1.06 × $62.48 = $66.23

_____

<em>Comment on the answer</em>

Whether you pay $66.23 or $66.22 depends on how the discount is calculated. If you get the benefit of the half-penny (the discount is rounded up), then the sale price is $62.47 and the total is $66.22.

Find the difference.<br>(2n - 9) - 5(-2.4n + 4) =​
MArishka [77]

Answer:

14n - 29

Step-by-step explanation:

First you'd distribute in the parentheses by -5. -5 × -2.4n and -5 × 4 which you would get 12 and -20.

Then, bring everything down and combine like terms. 2n + 12n = 14n || -9 - 20 or -9 - (-20) = -29. 14n - 29 is the lowest you can simplify because you can subtract a variable and a constant together.
