Mathematics: 56. In a specific region of the country, the amount of a customer s water bill, W, is directly proportional to the average daily temperature for the month, T, the lawn area, A, and the square root of F, where Fis the family size, and inversely proportional to the number of inches of rain, R. In dne month, the average daily temperature is 78°F and the number of inches of rain is 5.6. If the average family of four who has a thousand square feet of laws pays $72.00 for water for that month, estimate

Approximately

W=132.29

Step-by-step explanation:

W=k(TA√F)/R

T=78°F

R=5.6 inches

F=4

A=1000 square feet

W=$72

Solve for k

W=k(TA√F)/R

72=k(78*1000*√4)/5.6

72=k(78,000*2) / 5.6

72=k(156,000) / 5.6

72*5.6 =156,000k

403.2=156,000k

k=403.2/156,000

=0.002585

Solve for w when F=6, A=1500, T= 78, R=5.6 inches

W=k(TA√F)/R

W=0.002585(78*1500*√6) / 5.6

=0.002585(78*1500*2.4495) / 5.6

=0.002585(286,591.5) /5.6

=740.8390 / 5.6

=132.2927

W=132.2927

Approximately 132.29
