the Results
- How many seventh-grade students do not play a musical
instrument? - Suppose there had been 750 seventh-grade students.
a. What would you do differently in Step 2?
b. What is 60% of 750?
and Apply
- SCHOOL SPORTS The seventh-grade class at Fort Couch Middle School
had a goal of selling 300 tickets to the annual student-teacher basketball
game. The eighth-grade class had a goal of selling 400 tickets.
a. By the end of the first week, the eighth-grade students sold 30% of their
goal. Draw a bar diagram to represent this situation.
b. How many tickets had the eighth grade sold?
c. The seventh grade sold 40% of their goal. How many tickets do the
students still need to sell? Use a bar diagram to justify your solution. - ALLOWANCES The graph shows the results of a survey asking
500 teens about their allowances.
a. Draw a bar diagram to represent how many of the teens
received between $10 and $20 as a weekly allowance.
(Hint: Since 75% = _ 43 , divide the bar diagram into fourths.)
b. How many teens did not receive between $10 and $20?
Justify your solution. - SOCIAL STUDIES Reggie has memorized 60% of the 50 state
capitals for a social studies test.
a. Draw a bar diagram to represent how many state capitals Reggie has
memorized.
b. How many more capitals does he need to memorize before the test?
E WRITE MATH Write a real-world problem for each bar diagram. Then solve
your problem.
