Answer:

  • 3. 152
  • 4. $1479
  • 5. 36 students
  • 6. 30%

Step-by-step explanation:

Question 3

Members not using stepper or treadmill:

  • 15%+23%= 38%

38% of 400 is:

  • 38*400/100 = 152

Question 4

  • Amount of loan $24650
  • Interest rate 2%
  • Time 2 years

Amount of interest after 2 years:

  • $24650*2*3/100 = $1479

Question 5

Total number of students in the poll is 150

Students choosing tacos and corn dogs:

  • 12% + 12% = 24%

24% in number:

  • 150*24/100 = 36

Note. It says "how many more students" but its not applicable as there is nothing to compare. Consult this with your teacher.

Question 6

Normal cost of television = $500

Reduced cost = $350

Cost reduction:

  • $500 - $350 = $150

Percent reduction:

  • 150/500*100% = 30%
