Total amount of food waste generated in the two year is [tex]6.79\times 10^7\ \text{tons}[/tex]

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

[tex]37500000+30400000=67900000\ \text{tons}[/tex]

Let us check each option

[tex]67.9\times 10^{14}=6790000000000000[/tex]

[tex]6.79\times 10^7=67900000[/tex]

[tex]67.9\times 10^7=679000000[/tex]

[tex]6.79\times 10^{14}=679000000000000[/tex]
