1AUse the table to answer the question.
Rounding to the nearest dollar, which shows how to estimate the cost of purchasing five sport balls, one of each type?
A. $31.00 = $4 + $1 + $12 + $8 + $6B. $32.00 = $5 + $1 + $12 + $8 + $6C.$34.00 = $5 + $1 + $13 + $9 + $6D.$36.00 = $5 + $2 + $13 + $9 + $7
1BIn 1993, a group in Utica, New York, made a very large round jelly doughnut which broke the world record for doughnut size. It weighed 1.5 tons and had a circumference of 50 feet. Estimate the diameter of the doughnut.

7AUse the graph and table to answer the question.
The circle graph show the percent of students involved in each activity. The table shows the number of students in each activity. Which statement is caused by a misrepresentation of data in the circle graph?
A. Students are involved in clubs the least.B. Students are involved in music the most.C. Students are involved in three activities.D. Students are involved in 180 percent of the activities.
7B Use the graph below to answer the question.
What is wrong with this circle graph?
The sum of the percents is 100, which is correct. However, 30% and 20% appear to be the same size. 30% needs to be represented by a larger sector than 20%.
