Since i bought 1 tray of chips, and a cake, the equation is:
![$9.25 + 24 = 33.25](https://tex.z-dn.net/?f=%249.25%20%2B%2024%20%3D%2033.25)
Now for the pizza, since i bought 4 pizzas for 10.50 each, with 1/3 off. The equation is:
![10.50 * 4 = 42](https://tex.z-dn.net/?f=10.50%20%2A%204%20%3D%2042)
The special is 1/3 for the pizzas:
![1/3 * 42 = 14](https://tex.z-dn.net/?f=1%2F3%20%2A%2042%20%3D%2014)
Now adding the prices its:
![33.25 + 14 = 47.25](https://tex.z-dn.net/?f=33.25%20%2B%2014%20%3D%2047.25)
The total: $47.25

Let h be horses
let s be sheep
h + s = 28
6s = h
plug h into eq’n one
(6s) + s = 28
7s = 28
s = 4
plug s into eq’n 2
6(4) = h
24 = h
therefore there are 24 horses and 4 sheep
The correct answer is Choice A: 30.
To find the amount of interest, we have to use the formula for compounded interest.
It would be: y = 500(1 + 0.03/4)^(8)
We divided the 3% by 4 because it is quarterly. We raised it to the 8th power, because it will be compounded 8 times (4 x 2).
The interest comes out to $30.80.
