Your friend uses 5.5 gallons of gas each month mowing his lawn. Approximately how much CO2 pollution does this cause per month? (round to the tenths place) How much pollution does this create per year, assuming he mows 6 months per year? (round to the tenths place)

A typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year. This assumes the average gasoline vehicle on the road today has a fuel economy of about 22.0 miles per gallon and drives around 11,500 miles per year. Every gallon of gasoline burned creates about 8,887 grams of CO2.

I think this might help!

Step-by-step explanation:

the answer for the first question "per month" is 108.9

Step-by-step explanation:

so the formula in finding CO2 emission from burning gas is 19.8lb of co2 divided by 1 gallon of gasoline, this formula never changes, always stays the same.

5.5gallon/1 co2 multiplied by 19.8 co2/  1 gallon of gasoline equals 108.9

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
