—I went to visit my parents this past weekend in NJ.  They live 147 miles away from where I live in PA.  I always try to figure out how long it will take me to get there.  Most of the the drive is on the PA turnpike and I195, therefore, I can travel at least 65 mph.  I usually drive an average of 75 mph (oops).  About how long should it take me to get there?  I know that I can go 75 miles in one hour.  There for I can go 150 miles in 2 hours.  Since I am going 147, my answer will be close to 2 hours.

My friend Kelly and I went out for sushi today.  We had a total of $30 and it was $4.95 per sushi roll.  How many rolls of sushi could we get?  How much would we have left over? This is definitely a problem I would round.  Here is how we solved the problem.

Because the $4.95 does not go into $30 evenly, we round down.  Therefore, Kelly and I can get 6 rolls of sushi, 3 each! This will cost us $29.70.  $.30 left over.
