A small ice$-$cream parlor is equipped with a small freezer, a computer, and waffle cone maker. The freezer requires a power supply of $850W,$

works $24$ hours a day, and uses tetrafluoroethane $($also known as HFC$-134$ or R$134)$ as refrigerant gas. The waffle cone maker needs a power

supply of $1000W,$ but is switched on only $1$ hour a day. The computer requires $150W$ and is used during $8$ hours$/$day$.$ The parlor is also

furnished with three $20-$ W LED lamps that work $10$ hours a day.

Of note, they also know that, because of a mechanical failure, the freezer has been leaking some refrigerant to the atmosphere, at a rate of $1$

gram of R$134$ per day.

The ice$-$cream parlor also uses natural gas for boiling water and some baking. According to its natural gas provider, its bimonthly gas

consumption is approximately $40\frac{m^3}{b}$imester, or $20\frac{m^3}{m}$onth.

Furthermore, the parlor owns a Honda motorcycle for buying supplies and delivering take$-$out orders. The motorcycle runs on gasoline, has a

fuel efficiency of $30k\frac{m}{L},$ and travels $100k\frac{m}{?}$ day, on average.

Extra information

It is known that a vehicle $($including motorcycles$)$ releases $2\mathrm{.}2kg$ of $CO2$ per liter of gasoline.

$$ The Federal Commission on Electricity reported an emission factor for electricity production in Mexico of $0\mathrm{.}458\frac{t\text{c}\text{o}\text{z}\text{e}}{MWh}.$

The heating value of natural gas is $47M\frac{J}{k}g,$ and its density is $0\mathrm{.}8k\frac{g}{m^3}.$

You can consider a $30-$day month and$/$or a $4-$week month.
