Question

I need help with this question.

Answer 1

Let

x--------> the number of minutes

y-------> the total liters of water sold

we know that

y=150x

Divide 7,500 by 150

=(7,500/150)=50 minutes

Check

For x=50 minutes

Find the value of y

y=150*(50)=7,500 liters of water sold------> is ok

Find the domain

The domain will be the interval------> [0,50] minutes

Find the range

The range will be the interval------> [0,7,500] liters of water sold
