Write and solve an inequality for the following: a fish tank can hold at most 315 gallons of water. if a hose is filling the fish tank at a rate of 15 gallons every 10 minutes, how many hours can the hose be left on before the tank overflows?

Step 1

Find the unit rate

Step 2

Convert   to

we know that

so

Step 3

Find the inequality

Let

x--------> the time in hours

------> this is the inequality

Step 4

Solve the inequality

Divide by both sides

therefore

the answer is

Hose can be left on before tank overflows less than

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
