(A) 5a +10b -36
(B) 19p + 921
(C) -4a +7b
(D) 7x -9y + 10z
Best guess is it’s the second one but I believe it’s between A and B sorry If I’m wrong.
Answer: neither
Step-by-step explanation: because 64 kg and 640000g are equal masses.
So,
Our total will be equal to 20. If we want 1 additional topping, we will have an additional $1.25. <span>If we want 2 additional toppings, we will have an additional $2.50. So we can just multiply the number of additional toppings by 1.25 to get the additional amount.
1.25x
However, you will have already spent $15.
1.25x + 15 = 20
This is option B.
P.S. You will be able to put exactly 4 additional toppings.</span>
The answer is 10x^4 - 2x^3
