**First, you need to find 30% of 50. To do so, you have to turn 30% into a decimal by dividing 30 by 100.**

30% ⇒ 0.3

**Now, find 30% of 50 by multiplying 50 by 0.3.**

50 × 0.3 = 15

**30% of 50 is 15, so the discounted price of the shoes would be **<u>**$15.00**</u>**. **

**We aren't done yet though! We still need to factor in the tax. 1/2 of the sales tax, 8%, is 4%. Find 4% of 15 using the same process as before.**

4% ⇒ 0.04

**Multiply. **

0.04 × 15 = 0.60

**Add 0.60 to 15.**

0.60 + 15 = 15.60

<h2>Answer:</h2>

<u>You would pay </u>**<u>$15.60</u>**<u> for a pair of shoes with a regular price of $50.00.</u>

**Answer:**

110 degrees

**Step-by-step explanation:**

Because these angles are vertical, 5x+15=8x-42. thus, 15=3x-42, 3x=57, and x=19. 5x+15=5(19) +15=110. So, m<CDE=110 degrees.
