Use the table to solve. Luke went to the store to buy several items to make apple pie. How much will 5 pounds of apples cost him?
According to the table, each pound of apples costs 99 cents. He needs 5 pounds.
We can find the total cost by multiplying the cost per pound and the total number of pounds.
We can also find the answer by adding the cost of five individual pounds of apples.

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.
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.
Example Question #1 : How To Find The Answer From A Table
On 9 tests, Jeff scores 97, 91, 100, 85, 95, 87, 90, 98, and 84. What is the median of his test scores?
The median is the number that is in the middle when all of the elements are arranged in order from low to high:
84 85 87 90 91 95 97 98 100
(Note: remember that if there are an even number of elements, you average the two that are in the middle).

Example Question #1 : How To Find The Answer From A Table
Which city has the greatest range of the number of cats and dogs?
Cannot be determined
Miami
Duluth
Jonestown
Heathrow
Miami
Cats are represented by the blue bar, and dogs are represented by the orange bar. Therefore, we're looking for the biggest difference, or range, in the heights of the two bars. This occurs in Miami.
Example Question #2 : How To Find The Answer From A Table
How many cities have more cats than dogs?
1
Cannot be determined
2
4
3
2
To find the cities with more cats than dogs, look at the chart and see where the blue bar (cats) is greater than the orange bar (dogs). This only happens in Duluth and Pawnee, so the answer is 2.
Example Question #1 : How To Find The Answer From A Table
Between what two days did George's speed decrease?
Between February 12 and February 13
Between February 16 and February 17
Between February 10 and February 11
Between February 8 and February 9
Between February 14 and February 15
Between February 12 and February 13
On February 12, George's speed was 19.4 seconds, while on February 13, it was 19.3 seconds. This is the only decrease in the chart.
Example Question #4 : How To Find The Answer From A Table
By how many seconds did George's speed increase between February 8 and February 17?
18.2 seconds
3 seconds
1.4 seconds
2.5 seconds
21.2 seconds
3 seconds
To find the increase, subtract February 8's speed from February 17's speed: 21.2 seconds - 18.2 seconds = 3 seconds
