: 4. A ford expedition will travel 198 miles on 16.5 gallons of gasoline during city driving. What is the rate in miles per gallon? I divided 198 by 16.5 and got 12 mpg.
5. A package of 16 tea bags costs 2.29. Find the unit price in cents per tea bag. Round to the nearest tenth of a cent. I got 22.9 cents per bag.
16. Lia bought a new car. In the first 4 months, it was driven 3600 miles. At this rate, how many miles will the car be driven in 1 year? I tried doing the equation 4/3600=24/x my answers not coming out right.
Thanks for all the help.

You can put this solution on YOUR website! 4. A ford expedition will travel 198 miles on 16.5 gallons of gasoline during city driving. What is the rate in miles per gallon?
I divided 198 by 16.5 and got 12 mpg. You got this right
:
You can confirm this by asking "how far can I go on 16.5 gal, if I get 12 mpg
16.5 * 12 = 198 miles, right?

5. A package of 16 tea bags costs 2.29. Find the unit price in cents per tea bag. Round to the nearest tenth of a cent. I got 22.9 cents per bag.
:
Here something went wrong: 2.29 divided by 16 = .143 or 14.3 cents
:
Here again you can confirm this. "How much will 16 bags cost at .143 per bag?"
16 * .143 = 2.288 ~ 2.29; slightly different because we rounded it off.

16. Lia bought a new car. In the first 4 months, it was driven 3600 miles. At this rate, how many miles will the car be driven in 1 year? I tried doing the equation 4/3600=24/x my answers not coming out right.
:
You have the right idea here, however, I am not sure what you got 24 from. =
Cross multiply
4x = 12*3600
4x = 43200
x =
x = 10,800 in 12 months
:
Another way is find out how far in 1 month: 3600/4 = 900 mi per month
then 12 * 900 = 10800 mi in 12 months
:
I think you will be OK, just need a little help to get on the right track.
Hope I provided that. A
