2.

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 monthly costs for Gera family

Monthly costs = Rent + Telephone + Hydro.
Rent = $375$, Telephone = $7.35$, Hydro = $24.04\div2 = 12.02$.
So, monthly costs = $375+7.35 + 12.02$.

Step2: Calculate the sum

$375+7.35+12.02=394.37$.

Step3: Calculate money left over for Gera family

Money left over = Monthly Income - Monthly Costs.
Monthly Income = $795$, Monthly Costs = $394.37$.
So, money left over = $795 - 394.37$.

Step4: Calculate the difference

$795-394.37 = 400.63$.

Step5: Calculate monthly costs for Smith family

Rent = $410$, Telephone = $11.35$, Hydro = $26.26\div2=13.13$.
Monthly costs = $410 + 11.35+13.13$.

Step6: Calculate the sum

$410+11.35 + 13.13=434.48$.

Step7: Calculate money left over for Smith family

Monthly Income = $956$, Monthly Costs = $434.48$.
Money left over = $956-434.48$.

Step8: Calculate the difference

$956 - 434.48=521.52$.

Step9: Calculate monthly costs for Brown family

Rent = $355$, Telephone = $12.10$, Hydro = $28.24\div2 = 14.12$.
Monthly costs = $355+12.10 + 14.12$.

Step10: Calculate the sum

$355+12.10+14.12=381.22$.

Step11: Calculate money left over for Brown family

Monthly Income = $855$, Monthly Costs = $381.22$.
Money left over = $855-381.22$.

Step12: Calculate the difference

$855-381.22 = 473.78$.

Step13: Calculate monthly costs for Chang family

Rent = $620$, Telephone = $14.10$, Hydro = $24.66\div2=12.33$.
Monthly costs = $620+14.10+12.33$.

Step14: Calculate the sum

$620+14.10+12.33=646.43$.

Step15: Calculate money left over for Chang family

Monthly Income = $1049$, Monthly Costs = $646.43$.
Money left over = $1049-646.43$.

Step16: Calculate the difference

$1049-646.43 = 402.57$.

Step17: Calculate monthly costs for Geary family

Rent = $515$, Telephone = $12.85$, Hydro = $33.04\div2 = 16.52$.
Monthly costs = $515+12.85+16.52$.

Step18: Calculate the sum

$515+12.85+16.52=544.37$.

Step19: Calculate money left over for Geary family

Monthly Income = $1048$, Monthly Costs = $544.37$.
Money left over = $1048-544.37$.

Step20: Calculate the difference

$1048-544.37=503.63$.

Step21: Calculate monthly costs for Lockhart family

Rent = $495$, Telephone = $12.10$, Hydro = $26.02\div2=13.01$.
Monthly costs = $495+12.10+13.01$.

Step22: Calculate the sum

$495+12.10+13.01=520.11$.

Step23: Calculate money left over for Lockhart family

Monthly Income = $1015$, Monthly Costs = $520.11$.
Money left over = $1015-520.11$.

Step24: Calculate the difference

$1015-520.11 = 494.89$.

Step25: Calculate monthly costs for Stokes family

Rent = $725$, Telephone = $14.85$, Hydro = $39.04\div2=19.52$.
Monthly costs = $725+14.85+19.52$.

Step26: Calculate the sum

$725+14.85+19.52=759.37$.

Step27: Calculate money left over for Stokes family

Monthly Income = $1275$, Monthly Costs = $759.37$.
Money left over = $1275-759.37$.

Step28: Calculate the difference

$1275-759.37=515.63$.

Step29: Calculate monthly costs for Koszka family

Rent = $815$, Telephone = $14.85$, Hydro = $41.80\div2=20.9$.
Monthly costs = $815+14.85+20.9$.

Step30: Calculate the sum

$815+14.85+20.9=850.75$.

Step31: Calculate money left over for Koszka family

Monthly Income = $1250$, Monthly Costs = $850.75$.
Money left over = $1250-850.75$.

Step32: Calculate the difference

$1250-850.75 = 399.25$.

Step33: Calculate monthly costs for Burns family

Rent = $973$, Telephone = $12.10$, Hydro = $32.86\div2=16.43$.
Monthly costs = $973+12.10+16.43$.

Step34: Calculate the sum

$973+12.10+16.43=991.53$.

Step35: Calculate money left over for Burns family

Monthly Income = $1485$, Monthly Costs = $991.53$.
Money left over = $1485-991.53$.

Step36: Calculate the difference

$1485-991.53=493.47$.

Step37: Calculate monthly costs for O’Malley family

Rent = $524$, Telephone = $7.35$, Hydro = $22.86\div2=11.43$.
Monthly costs = $524+7.35+11.43$.

Step38: Calculate the sum

$524+7.35+11.43=542.78$.

Step39: Calculate money left over for O’Malley family

Monthly Income = $1175$, Monthly Costs = $542.78$.
Money left over = $1175-542.78$.

Step40: Calculate the difference

$1175-542.78 = 632.22$.
