Answer:
493.2 · 10⁸
Step-by-step explanation:
1 person = 180 bars
274,000,000 people · 180 bars per person
274,000,000 can be simplified to 274 · 10⁶
274 · 180 = 49320 · 10⁶
Now transferring this to scientific notation by moving the decimal two spaces to the left
493.2 · 10⁶ + 10² The 10² is for the two spaces to the left
493.2 · 10⁸
