Question

A golf course in Phoenix, Arizona, uses an average of 80 million gallons of water daily for irrigation. An average family of four (also living in Phoenix, AZ) uses 325,851 gallons of water per year. Rounded to the nearest ten, how many families of four can one golf course provide water for?

Answer 1

Answer:

89610 family

Step-by-step explanation:

An average family of four (also living in Phoenix, AZ) uses 325,851÷365 gallons of water per day

then

An average family of four (also living in Phoenix, AZ) uses 892.74247 gallons of water per day

therefore

the number of families of four can one golf course provide water for :

80 000 000÷892.74247=89611.509

the number of families of four can one golf course provide water for :

[rounded to the nearest ten] 89610.

Around 250 families can be provided with one golf course.

Step-by-step explanation:

Givens

• A golf course uses 80 million gallons of water daily.
• A family of four uses 325,851 gallons of water per year.

This situation can be described by the following equation

$325,851x=80,000,000$

Where $x$ indicates the number of families that could use the 80 million galons of water.

Let's solve for $x$

$x=\frac{80,000,000}{325,851}\\ x \approx 250$

Therefore, around 250 families can be provided with one golf course.
