I don’t know what you mean. Are you talking about the fact that x is an unknown number or the fact that there are 4 “terms” in one and 3 in the other?

If a stereo is sold for $59.99 and Karen pays $64.19 for it when she checks out, what is the sales tax in the area
pogonyaev
Okay, so the first thing you need to do is find the difference.

64.19 - 59.99 = 4.20

So the percentage is determined by dividing that difference by the cost of the item originally:

4.20 / 59.99 = about .07

Next, you change this number to a percentage by moving the decimal to the right two spaces, so that would be 7%.

Therefore, the sales tax in the area is 7%.

A. 44<br> B. 112<br> C. 32<br> D. 35
Gwar [14]

Answer:

A. 44

Step-by-step explanation:

The area of a trapezoid is \frac{b_1+b_2}{2} * h, where b_1 and b_2 are the top and bottom bases, and h = height. We are given the bases as 8 and 14, and the height as 4.

  • \frac{8+14}{2} *4
  • \frac{22}{2} *4
  • 11*4
  • 44

Therefore, the answer is A. 44.
