In the first 25% of the produce, 7% of that is defective. Which means that 25%*93% is not defective.
=20.75% not defective.
In the second 30% of the produce, 6% is defective Which means that 30%*94%
=28.2% not defective
Now for the 3rd 45% of the produce, 4% is defective which means that
45%*96%
=43.2% not defective.
Added together, 20.75+28.2+43.2=92.15% not defective.

Step-by-step explanation:
A factory makes rectangular sheets of cardboard, each with an area 2 1/2 square feet. Each sheet of cardboard can be cut into smaller pieces of cardboard measuring 1 1/6 square feet. How many smaller pieces of cardboard does each sheet of cardboard provide?
Each sheet of cardboard = 2 1/2 square feet
Each smaller pieces of cardboard = 1 1/6 square feet
Number of smaller pieces of cardboard per sheet of cardboard = Each sheet of cardboard ÷
Each smaller pieces of cardboard
= 2 1/2 square feet ÷ 1 1/6 square feet
= 5/2 ÷ 7/6
= 5/2 × 6/7
= (5*6) / (2*7)
= 30/14
= 15/7
= 2 1/7 pieces
Number of smaller pieces of cardboard per sheet of cardboard = 2 1/7 pieces
