Answer 1

Answer:

2.

% increase = (396 - 148) / 148 × 100

= 148/148 × 100

= 100 % increase

3.

% decrease = (94 - 23.5) / 94 × 100

= 70.5 / 94 × 100

= 75 % decrease

4.

% of good bulbs = (12-4) / 12 × 100

= 8/12 × 100

= 66.66%

5.

% decrease = (58 - 50) / 58 × 100

= 8/58 × 100

= 13.80% decrease

6.

% of books sold out = 2640 / 12000 × 100

= 22 %
