Ben conserves water in his home.He conserves 3 gallons each time he turns off the faucet when brushing his teeth.He conserves 30 gallons by running the dishwasher once a day instead of twice a day. What expression represents the total number of gallons,g,Ben saves each day?

3g+30 or. 30g+30

I passed this question by because we don't know how many times he brushes his teeth each day.

I think it is 3G+30. I can't figure out the situation problem.I'm good at subtraction situations but I keep drawing a blank on the addition.

• Ms.Sue - ,

Assuming he brushes his teeth only once a day, the expression would be

3 + 30 = g

It doesn't give me that as an option.I have another question.
Write an situation that can be represented by 6n+4.
Is this right?
Brooke has n number of coins that are worth \$6 each.If she also has 4 dollar bills in her purse,how much does she have in total?

• Ms.Sue - ,

For the second one. The U.S. doesn't have any coins worth \$6.00 each. The largest coin is \$1.00

Try that one again!

• Ms.Sue - ,

The options are
3G-30
3G+30
30g+3
30g-3

• Ms.Sue - ,

3G + 30 is right.
