Answer:
The minimum number of hats which team need to sell t make enough money for the trip is 21 .
Step-by-step explanation:
Given as :
The money which team needs for the trip = $ 425
The money which team already = $ 175
So, The rest money which team need = $ 425 - $ 175 = $ 250
Now, The sell price for the hats = $ 12
Let The minimum number of hats which team need to sell = x
So, According to question
∵ The rest money which team need = $ 250
The selling price of each hats = $ 12
Or, The minimum number of hats which team need to sell = ![\dfrac{\textrm Rest money which team needs}{\textrm The selling price of each hats}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctextrm%20Rest%20money%20which%20team%20needs%7D%7B%5Ctextrm%20The%20selling%20price%20of%20each%20hats%7D)
Or, x = ![\frac{250}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B250%7D%7B12%7D)
∴ x = ![\frac{250}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B250%7D%7B12%7D)
I.e x = 20.8
So, The minimum number of hats need to be sell = 20.8 ≈ 21
Hence The minimum number of hats which team need to sell t make enough money for the trip is 21 . Answer
