Question

12. The price of a machine of a factory is 18000. The price of that machine decreases by
50% in each year. Let us calculate its price after 3 years. ​

Answer 1

Answer:

2250

Step-by-step explanation:

50% means half so half of 18000 is 9000 of first year and half of 9000 is 4500 of second year and half of 4500 is 2250 of third year

Answer 2

Answer:

50/100×18000

1/2×18000 = 9000

then,finding second year

50/100×9000

1/2×9000=4500

now finding third year

50/100×4500

1/2×4500 = 2250
