Answer:

d. 1,196,000 gal

Explanation:

Question:

Turner Middle School has 525 boys, 625 girls, 58 teachers, and a supporting staff of 12 employees. The school uses an average of 1,267,760 gallons of water per month. Assuming that the water usage is proportional to the number of people in the school, about how much water do the students consume per week? a. 17,940 gal c. 316,940 gal b. 299,000 gal d. 1,196,000 gal

Answer:

Total number of people:

525 + 625 + 58 + 12 = 1220

Total number of students:

525 + 625 = 1150

Proportion:

1220 people are to 1,267,760 gallons as 1150 people are to x gallons

1220/1,267,760 = 1150/x

1220x = 1,267,760 × 1150

x = 1,267,760/1220 × 1150

x = 1,195,019.6

Answer: d. 1,196,000 gal
