To calculate Macy's monthly utility bill, we need to consider the cost of electricity, gas, water, phone, and internet, then sum these costs up to get the total.
1. Electricity Cost:
- Electricity usage: 235 kwh
- Rate: \[tex]$0.15 per kwh
\[
\text{Electricity Cost} = 235 \text{ kwh} \times 0.15 \text{ \$[/tex]/kwh} = 35.25 \text{ \[tex]$}
\]
2. Gas Cost:
- Gas usage: 925 ft³
- Rate: \$[/tex]1.00 per 100 ft³
[tex]\[
\text{Gas Cost} = \left(\frac{925 \text{ ft}^3}{100}\right) \times 1.00 \text{ \$/100 ft}^3 = 9.25 \text{ \$}
\][/tex]
3. Water Cost:
- Water usage: 425 gallons
- Rate: \[tex]$0.03 per 10 gallons
\[
\text{Water Cost} = \left(\frac{425 \text{ gallons}}{10}\right) \times 0.03 \text{ \$[/tex]/10 gallons} = 1.27 \text{ \[tex]$}
\]
4. Phone Cost per Month:
- Flat rate: \$[/tex]40 per month
[tex]\[
\text{Phone Cost} = 40.00 \text{ \$}
\][/tex]
5. Internet Cost per Month:
- Flat rate: \[tex]$100 per month
\[
\text{Internet Cost} = 100.00 \text{ \$[/tex]}
\]
6. Maintenance Cost per Month:
Because Macy pays no maintenance costs, the maintenance cost is:
[tex]\[
\text{Maintenance Cost} = 0.00 \text{ \$}
\][/tex]
7. Total Monthly Utility Bill:
Now, sum up all the calculated individual costs.
[tex]\[
\text{Total Monthly Utility Bill} = 35.25 \text{ \$} (\text{Electricity}) + 9.25 \text{ \$} (\text{Gas}) + 1.27 \text{ \$} (\text{Water}) + 40.00 \text{ \$} (\text{Phone}) + 100.00 \text{ \$} (\text{Internet}) + 0.00 \text{ \$} (\text{Maintenance})
\][/tex]
[tex]\[
\text{Total Monthly Utility Bill} = 185.78 \text{ \$}
\][/tex]
Therefore, Macy's monthly utility bill is \$185.78, rounded to the nearest cent.
