We need to find the total food waste generated over the two years.

Total amount of food waste generated in the two year is \(6.79\times 10^7\ \text{tons}\)

Food waste generated in one year = 37500000 tons

Food waste generated in the next year = 30400000 tons

Total food waste generated in the two years is

\(37500000+30400000=67900000\ \text{tons}\)

Let us check each option

\(67.9\times 10^{14}=6790000000000000\)

\(6.79\times 10^7=67900000\)

\(67.9\times 10^7=679000000\)

\(6.79\times 10^{14}=679000000000000\)

So, the correct option is \(6.79\times 10^7\ \text{tons}\)
