Question

75% of the apple pies were sold on Tuesday and the remainder thrown out. If 12 apple pies were sold Tuesday, how many were thrown out?

Answer 1

ok

75 ----------------------- 12

100 ----------------------- x

x = (100 x 12) / 75

x = 1200 / 75

x = 16

In total there were 16 pies.

12 pies were sold out and 4 (16 - 12) were thrown away.

The answer is 4 pies

2) 8000 ------------------------- 100%

x ------------------------- 16%

x = (16 x 8000) / 100

x = 128000/100

x = 1280

It sold 1280 tickets as reserved
