Question

There are 10 gallons of water in a tank. Each minute, 4 more gallons are added. The volume of the water in a tank after t minutes is V (gallons). What is the formula for the dependence of V on t (t≤10)?

Answer 1

Answer:

V = 10 + 4t

Step-by-step explanation:

To find the equation, look at the pattern:

• 10 gallons + 4 gallons = 14 gallons after 1 minute
• 10 + 4 + 4 = 18 after 2 minutes
• 10 + 4+4+4 = 22 after 3 minutes.

The pattern is 10 + 4 (t) = V
