24. This answer would be A, or y=x^4. When the exponent is used, in each ordered pair, every time x is increased by 1, y is multiplied by 4, like in every exponent. 1 x 4 = 4. 4 x 4 = 16. 16 x 4 = 64. 64 x 4 = 256.

25. The answer is C, or C(n) = (0.90 + n) - 0.40. Your coupon subtracts 40 cents off of your total amount of cans of tuna, but the amount of tuna cans that you will buy is not stated, so that unknown number is n.
