Question

mr. ramsey just finished bathing his kids, and now he is draining the tub. the tub contains 32 gallons of water and is draining at a rate of 3 gallons per minute. write an equation that shows how the number of gallons remaining y, depends on the number of minutes the tub has been draining, x.

Explanation:

Step1: Identify initial amount and rate

The initial amount of water is 32 gallons and the rate of draining is 3 gallons per minute.

Step2: Use linear - equation form

The general form of a linear equation for this situation is $y = \text{initial amount}-\text{rate}\times x$. Here, the initial amount is 32 and the rate is 3. So the equation is $y=32 - 3x$.

Answer:

$y = 32-3x$
