water: $ billed per unit $0.08/10 gal, usage 4,400 gallons, amount due $35.20
gas: $ billed per unit $1/100 cubed ft, usage 6,200 cubed feet, amount due $?
phone lines: $ billed per unit $39/line, usage 7 lines, amount due $273.00

internet service: $ billed per unit $215/month, usage flat charge per month, amount due $215.00

Explanation:

Step1: Calculate the number of 100 - cubed - ft units for gas

The usage of gas is \(6200\) cubed feet. To find the number of \(100\) - cubed - ft units, divide the total usage by \(100\).
\(\frac{6200}{100}=62\)

Step2: Calculate the amount due for gas

The cost per \(100\) - cubed - ft unit is \(\$1\). Multiply the number of units by the cost per unit.
\(62\times\$1=\$62\)

Answer:

\(\$62\)
