Answer:
c = (y-0.13y)(1.08)
Step-by-step explanation:
c = cost and y = the original price
The amount of money off is 13% of y, or 0.13 of y. You would subtract that from y to get the price of the cards with the discount. For final cost, you need the cost of the cards (1) plus the cost of tax (8%, or 0.08). 1+0.08 is 1.08, so that's what you would multiply y by to get the final cost of the cards.

Answer: Choice A</h3>
-425 < 212
==========================================================
Explanation:
Draw a horizontal number line with negative numbers on the left, and positive on the right. Therefore, -425 is to the left of 212. In turn this means -425 is smaller than 212
Alternatively, draw a vertical number line. Think of 0 as the ground, positive numbers above ground, and negative numbers below ground. With 212 higher than -425, we know that 212 is larger than -425; i.e. -425 is smaller than 212
