pricing
the cost of a product to a retailer is $3.40.
If the ratailer wishes to make a profit of 20%
on the selling price * at what price should the product
sold???use the rule

pricing =cost + profit

آنا وصلت لين هذا الحل وما عرفت اكمل

price =cost+profit

p=price

p= 3.40 + (20%p x 3.40)

[نورالعين]

The cost ---- the profit --- the selling
120% ----------- 20% -------- 100%
3.04

So if we need the profit only = (3.40 x 20) /100= 0.68

If we need the selling price = (3.40 x 120) /100= 4.04

What you do is right but you have to replace 20% with 20/100
I hope you understand
Best Regards

خلااص عرفت الحل مشكورين للي حاولو يساعدوني


s = 3.40+ 20/100s
s= 3.40+ 0.2s
s-0.2s= 3.40
0.8s=3.40
s = 3.40/0.8
s=4.25$
