Question

The amounts of food waste generated in a region during two years were 37,500,000 tons and 30,400,000 tons. What was the total food waste generated over these two years in the region, expressed in scientific notation?

Group of answer choices

6.79 ⋅ 107 tons

67.9 ⋅ 107 tons

67.9 ⋅ 1014 tons

6.79 ⋅ 1014 tons

Answer 1

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**
