Adam McNamara I got
this answer by adding 214+563+471+834 to find the total number of
tickets and came up with 2082. Then I used the picture way to divide
the number by 3. First I used 600 and subtracted 1800 from 2082 and
had 282 left. Next, I used 90 and only had 12 left. Finally, I
divided 12 by 3 and got 4. So one third of 2082 is 694.
Problem of the Week #4 Answer: They made
$482.65 before figuring supplies and $348.38 after.
If Mr. Frost's class made $192.50 on the
sundae sale, 83.75 on the raffle, and Mr. Dunn's class made $206.40
on the bake sale, how much did they make total? If they spent
$134.27 on materials, how much did they actually make?
Sarah Coyne
Mr. Frost = sundaes $192.50
raffle +$ 83.75
total for Mr. Frost=$276.25
Mr. Dunn=Bake sale $206.40
Total Mr. Frost and Mr. Dunn=$482.65
subtract materials = - $134.27
Total all together= $348.38
Problem of the Week #3 Answer: 66 hours
If all 18 students read for 1 hour each on
Monday, Tuesday, and Wednesday, and for 40 minutes on Thursday, how
much time did the whole class spend reading from Monday to Thursday?
Nolan McKenney
Explanation:
18 students x 1 hour x 3 days= 54 hours.
40 mins x 18 students =720 mins /60 mins =12 hours.
54 hours + 12 hours =66 hours.
Problem of the Week # 2 Answer: 8 hours 13
minutes & 16 inches
A snowstorm hit the Marshfield area at 5:25
p.m. Thursday night and lasted until 1:38 a.m.? During the storm,
the snow came down at an incredible rate of 2 inches an hour. How
long did the storm last? About how much snow did Marshfield get?
Rachael K. Explanation:
I got this answer bye figuring out how much time between 5:25 and
1:25 and got 8 hours. Then I found out how much time between 1:25
and 1:38 and got 13 minute lastly I added up the hours and minutes
and got 8 hours 13 minutes.
I got this answer because I multiplied 8x2 and got 16 inches.
Abby H. Explanation:
First,I kept adding on hours and minutes to 5:25 p.m. To get
from 5:25 p.m. to 1:38 a.m., it is 8 hr. 13 min. Then, I multiplied
2x8 because about 2 inches of snow fell for 8 hours. This would mean
that there was 16 inches of snow. Also, it snowed for 8 hours,13
minutes.
Problem of the Week #1 Answer: $9.18
Imagine that all 18 students in our class
were to send a letter to a relative in the United States to find out
more about them. Each student had to pay $.41 in postage and $.10
for an envelope. How much would the whole class have spent on the
letters?
Rachael K.
Explanation:
First I multiplied .41 and 18 because there are 18 kids in the class
as it said. I multiplied the .41 because it also said it in the
problem. I got $7.38. Next I multiplied 18 and .10 and got $1.80.
Lastly I added 1.80 and 7.38 and got $9.18.
