Answer:
A) 12.48 million
Step-by-step explanation:
To solve this problem, we need to figure out what 26% of 48 million is. We will need to multiply 48,000,000 by 26% to get our answer. Don't forget that we will also need to switch 26% to its decimal form (26% - > 0.26).
48,000,000 x 0.26 = 12,480,000
Our answer is 12,480,000 or in other terms $12.48 million. This means that A is the best answer.
