19] After increasing the price of an article by 20%. The price was GHC 3000.00. What was the original price?

Step-by-step explanation:

Let the original price be x

After increasing by 20% the price is 3000

Thus,

x + ( x × 20%) = 3000

x + 20x/100 = 3000

x + x/5 = 3000

(5x + x)/5 = 3000

6x/5 = 3000

x = 3000 * 5/6

x = 2500

Hope it helps :)

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

it is impossible.
