Question

Mrs. Kimpton had the students in her crafts class sew pillows. She inspected each pillow to make sure it was satisfactory before accepting it as complete.

After the first inspection, she accepted 25% of the pillows as complete, and asked the rest of the students to make corrections. On her next inspection, she accepted 75% of those that remained.

If there are 32 students in the class, how many pillows has Mrs. Kimpton accepted after two inspections?

Answer 1

Assuming each students makes 1 pillow

  In first inspection accepted = 25 % of 32 = 1/4( 32) = 8 (Remaining = 32 - 8 = 24 )

 

In the second inspection 75 % of remaining = 3/4 of 24 = 3/4 (24) = 18

 Total accepted = 8 + 18  = 26 

Answer 2

25% of 32 is:

 

.25 x 32 = 8

 

meaning 8 were completed and 32 - 8 = 24 remained

 

75% of 24 is:

 

.75 x 24 = 18

 

meaning 18 were completed in the 2nd round

 

Therefore 8 + 18 = 26 were completed after 2 inspections.
