The water at the end of a pier was 28 meters deep at midnight. As the tide came in, the water depth increased at a rate of 0.012 meters per minute. Which equation can be solved to find t, the time in minutes it took the water depth to reach 30 meters?
(t/0.012) - 28 = 30
0.012t + 28 = 30
(t/0.012) + 28 = 30
0.012t – 28 = 30

Answer:

  0.012t + 28 = 30

Step-by-step explanation:

The depth starts at 28 meters. The amount of increase in t minutes will be 0.012t, so the total depth after t minutes is ...

  0.012t +28

We want to find when that is equal to 30, so the appropriate equation is ...

  0.012t +28 = 30
