Complete the table and write a linear equation

Question

A water tank contains 600 gallons of water and is leaking at a rate of 15 gallons per minute. Complete the table AND write a linear equation representing the volume of the tank of water, V, over time,t, in minutes.

1. the table has the numbers 0,1,2,3,4 on the left but is incomplete, finish the table
2. write a linear equation that represents the volume of the tank of water over time in minutes

Answer 1

Y= -15x +600

X. y

0 600

1 585

2 570

3 555

4 540

5 525

Tank will be empty when -15x+600=0

-15x =-600

X= -600/-15=40 minutes
