While researching, Ichiro found that a gasoline car can drive 210,000 miles on average over

its lifetime (period of time a car can operate).

A plug-in hybrid car can drive a lifetime of

300.000 miles.

Consider two families that each drive 15.000

miles a year for the lifetime of the car one

with a gasoline car and the other with a plug-in

hybrid.

What is the percent decrease for the pounds

of CO2 that the plug-in hybrid car would emit

over its lifetime as opposed to the gasoline car?

Round your final percentage to the nearest

integer.
