Question

step 2. toyota corolla hybrid (gas)

1. gallons used per year = 12,000 / 47 = ______ gallons
2. annual fuel cost = gallons × $1.80 = $ ______

step 3. tesla y (electric)

1. kwh per mile = 75 / 330 = ______ kwh/mile
2. annual energy use = 12,000 × (kwh per mile) = ______ kwh
3. annual charging cost = kwh × $0.16 = $ ______

fill in table 1

Explanation:

Step1: Calculate gallons used per year for Toyota Corolla Hybrid

The formula for gallons used per year is $\text{Gallons used per year}=\frac{\text{Miles driven per year}}{\text{Miles per gallon}}$. Given miles driven per year is $12000$ and miles per gallon is $47$. So, $\text{Gallons used per year}=\frac{12000}{47}\approx255.32$ gallons.

Step2: Calculate annual fuel cost for Toyota Corolla Hybrid

The formula for annual fuel cost is $\text{Annual fuel cost}=\text{Gallons used per year}\times\text{Cost per gallon}$. Cost per gallon is $\$1.80$. So, $\text{Annual fuel cost}=255.32\times1.80 = 459.58$ (rounded to two - decimal places).

Step3: Calculate kWh per mile for Tesla Y

The formula for kWh per mile is $\text{kWh per mile}=\frac{\text{Total kWh}}{\text{Total miles}}$. Given total kWh is $75$ and total miles is $330$. So, $\text{kWh per mile}=\frac{75}{330}\approx0.227$ kWh/mile.

Step4: Calculate annual energy use for Tesla Y

The formula for annual energy use is $\text{Annual energy use}=\text{Miles driven per year}\times\text{kWh per mile}$. Miles driven per year is $12000$. So, $\text{Annual energy use}=12000\times0.227 = 2724$ kWh.

Step5: Calculate annual charging cost for Tesla Y

The formula for annual charging cost is $\text{Annual charging cost}=\text{Annual energy use}\times\text{Cost per kWh}$. Cost per kWh is $\$0.16$. So, $\text{Annual charging cost}=2724\times0.16=\$435.84$.

Answer:

Toyota Corolla Hybrid:

• Gallons used per year: $\approx255.32$ gallons
• Annual fuel cost: $\$459.58$

Tesla Y:

• kWh per mile: $\approx0.227$ kWh/mile
• Annual energy use: $2724$ kWh
• Annual charging cost: $\$435.84$
