Cory ordered 28 black balloons and 28 silver balloons for a graduation party. If 9 of them pop, he will have
balloons left. A. 45 B. C. 47 D. 48
To solve this problem, we need to subtract the number of popped balloons from the total number of balloons.
First, let's find the total number of balloons Cory ordered:
28 black balloons + 28 silver balloons = 56 balloons
Next, let's subtract the 9 popped balloons from the total:
56 balloons - 9 popped balloons = 47 balloons
Therefore, Cory will have 47 balloons left. So the correct answer is option C.
