Explanation:
This is a percent change problem. The CO2 emitted by a car using gas is 4.7 MMt per year. The CO2 emitted by a car using corn ethanol made from biomass is 52% less than 4.7 MMt.
Find 52% of 4.7 MMt:
0.52 × 4.7 = 2.444.
Subtract 2.444 MMt from 4.7 MMt:
4.7 − 2.444 = 2.256.
The solution is 2.256 MMt.
