The amounts of plastic waste generated in a region during two years were 32,400,000 tons and 20,300,000 tons. what was the total plastic waste generated over these two years in the region, expressed in scientific notation?
a.52.7 ⋅ 1014 tons
b.52.7 ⋅ 107 tons
c.5.27 ⋅ 107 tons
d.5.27 ⋅ 1014 tons

the answer is a if my teacher taught me correct

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.

you!
