To find the total food waste generated over the two years, we need to add the amounts:
37,500,000 tons + 30,400,000 tons
First, let's calculate the sum:
37,500,000 + 30,400,000 = 67,900,000 tons
Now we need to express this total in scientific notation.
67,900,000 can be expressed as:
6.79 × 10^7 tons
So, the correct answer is:
6.79 ⋅ 10^7 tons
