Question

Grocery ItemPrice per UnitNumber of Units NeededTotal Amount
Apples$0.99 per pound5x
Pie crust$2.49 per package2$4.98
Butter$3.29 for 2 sticks2$6.58

Use the table to solve. If Luke needed to buy 2 more sticks of butter, for a total of 6 sticks of butter, how much money would he need to bring to the store to buy all the items? Round to the nearest dollar.

Answer

To buy all the items listed, he will need the sum of all the costs.

For apples, the cost is $0.99 per pound and he needs 5 pounds.

The apples will cost $4.95.

The total amount for the pie crusts is $4.98 in the table.

For butter, we need to find the cost of 6 sticks. In the table, 2 sticks of butter cost $3.29. Six sticks will cost three times as much.

The butter will cost $9.87.

Now, we need to add all the costs together.

When you add these items up, you get $19.80. Then, round to the nearest whole dollar. We need to round up, giving us $20.

Luke will need to bring $20 to buy all the items he needs for the apple pies.

Based on the graph, which question can be answered?

Based on the table above, which question can be answered?

Answer

The chart gives us information about George's run times in a specific period of time: February 8 through February 17. While cheetahs may be faster than humans, the chart cannot answer that; it also does not say whether cheetahs have spots, or how fast George ran on February 18.

Question

Use the following table to answer the question.

Table1

Which student has the most books?

Answer

When looking at the following table

Table1

We can see the first column is a list of students. The second column is a list of numbers of books. So, we can see the names of each student. Next to each name, is a number. This number is the number of books that student has.

So, if we are trying to find the student with the most books, we will first locate the largest number. That number is 5. Now, we will see which name is written next to that number. We see that it is Emma.

Therefore, Emma has the most books.

Question

Use the following table to answer the question.

Table5

Fill in the missing information.

Answer

If we look at the table

Table5

we can see the first column is a set of numbers. The second column is taking the numbers and squaring them.

For example, let's look at the first row. We have the number 1. When we square 1, , we get 1.

Let's look at the second row. We have the number 2. When we square 2, , we get 4.

Let's look at the third row. We have the number 3. When we square 3, , we get 9.

And so on....

So, to find the missing information, we take the first number and square it. So, we have the number 6. When we square 6, , we get 36.

Therefore, the missing information is 36.
