Question

note - the \monthly costs\ total will vary each month. electricity consumption could rise or lower. there could be long distance calls. all calculations on this page then should be considered estimates.

1. calculate the monthly costs for these families.

2.
(k) what other monthly expenses will each family have?

1. the brown family, in question 2, would like to buy a car. it would cost them $195.73/month. can they afford the car?

Explanation:

Step1: Calculate Hydro (for 2 months) ÷ 2 for each family

For family Smith: \(26.26\div2 = 13.13\)
For family Brown: \(28.24\div2=14.12\)
For family Chang: \(24.66\div2 = 12.33\)
For family Geary: \(33.04\div2=16.52\)
For family Lockhart: \(26.02\div2 = 13.01\)
For family Stokes: \(39.04\div2=19.52\)
For family Koszka: \(41.80\div2 = 20.9\)
For family Burns: \(32.86\div2=16.43\)
For family O'Malley: \(22.86\div2 = 11.43\)

Step2: Calculate Monthly costs for each family

For family Smith: \(410+11.35 + 13.13=434.48\)
For family Brown: \(355+12.10+14.12 = 381.22\)
For family Chang: \(620+14.10+12.33=646.43\)
For family Geary: \(515+12.85+16.52 = 544.37\)
For family Lockhart: \(495+12.10+13.01=520.11\)
For family Stokes: \(725+14.85+19.52=759.37\)
For family Koszka: \(815+14.85+20.9=850.75\)
For family Burns: \(973+12.10+16.43=1001.53\)
For family O'Malley: \(524+7.35+11.43=542.78\)

Step3: Calculate Money left over after monthly costs ( for families in part 2)

For family Smith: \(956 - 434.48=521.52\)
For family Brown: \(855-381.22 = 473.78\)
For family Chang: \(1049-646.43=402.57\)
For family Geary: \(1048 - 544.37=503.63\)
For family Lockhart: \(1015-520.11 = 494.89\)
For family Stokes: \(1275-759.37=515.63\)
For family Koszka: \(1250-850.75 = 399.25\)
For family Burns: \(1485-1001.53=483.47\)
For family O'Malley: \(1175-542.78=632.22\)

Step4: Determine if Brown family can afford the car

The Brown family has \(473.78\) left over after monthly costs. Since \(473.78>195.73\), they can afford the car.

(a) Gere: Monthly costs \(\$394.37\), Money left over \(\$400.63\)
(b) Smith: Monthly costs \(\$434.48\), Money left over \(\$521.52\)
(c) Brown: Monthly costs \(\$381.22\), Money left over \(\$473.78\)
(d) Chang: Monthly costs \(\$646.43\), Money left over \(\$402.57\)
(e) Geary: Monthly costs \(\$544.37\), Money left over \(\$503.63\)
(f) Lockhart: Monthly costs \(\$520.11\), Money left over \(\$494.89\)
(g) Stokes: Monthly costs \(\$759.37\), Money left over \(\$515.63\)
(h) Koszka: Monthly costs \(\$850.75\), Money left over \(\$399.25\)
(i) Burns: Monthly costs \(\$1001.53\), Money left over \(\$483.47\)
(j) O'Malley: Monthly costs \(\$542.78\), Money left over \(\$632.22\)
(k) Other monthly expenses could include food, clothing, transportation (not car in Brown's case yet), savings, entertainment etc.
(3) Yes, the Brown family can afford the car.
