2. Problem #1
My mom gave my brother, my sister, and me $20 for ice cream. Tax was 5%, which means we needed to add 5% to the cost of the ice cream to get the total payment. Can we all get ice cream sundaes?
Ice Cream
Single Scoop $3.50
Double Scoop $4.50
Ice Cream Sundae $6.00

3. Problem #2
We stopped for popcorn on the boardwalk at the beach. The large bucket of popcorn holds 12 cups of popcorn and costs $ The small bucket holds 3 cups of popcorn and costs $ Which bucket of popcorn is a better buy?

4. Problem #3 Condo Blueprint
I went to the beach this summer and my family stayed in a condo. This is a quick drawing of our condo. There are 5 people in our family. My mom said we each need 100 square feet of space in order to not argue. Is this condo big enough for my family?

5. Answer Key Solution #2 Solution #1
The small bucket holds 1/4 of the big bucket, because
3 cups ÷ 12 cups = 1/4. This means
that 4 small buckets = 1 big bucket.
Divide the price of the big bucket by 4 to get the price of the number of cups of popcorn (3) that are in the small bucket. $16 ÷ 4 = $4.
The big bucket costs $4 for 3 cups of popcorn, and the small bucket costs $4.50 for 3 cups of popcorn, so the big bucket is a better buy.
First figure out the cost of 3 ice cream sundaes. $6 x 3 = $18.
Next, calculate the tax. 10% (or 1/10) of $18 is $ % is half of 10%, and half of $1.80 is $0.90. So the tax was $0.90.
Then add the cost of the ice cream plus the tax. $18 + $0.90 = $18.90.
$18.90 is less than $20, so we could all have ice cream sundaes.

6. Answer Key: Solution #3 First, divide the drawing into rectangles.
10 ft
20 ft
5 ft
15 ft
3 ft
16 ft
First, divide the drawing into rectangles.
Second, figure out the length of each missing side. The length of first missing side was 10 ft because 20 – 5 – 5 = 10. The second missing side was the same length as the first because it is a rectangle and the two opposite sides of a rectangle are the same length. The third missing side was 16 ft because = 16.
Third, figure out the area of each rectangle.
Rectangle A = 20 x 10 = 200 sq ft
Rectangle B = 15 x 10 = 150 sq ft
Rectangle C = 10 x 16 = 160 sq ft
Fourth, add the areas of each rectangle to find out the total area of the condo.
= 510 sq ft.
The condo is big enough for my family. We needed at least 500 sq ft total, and the condo is 510
sq ft, which is bigger than what we needed. A C
10 ft B
