To Find : Approximately, how many shields and masks can the NGO purchase within the same budget
Solution:
purchased
20,000 masks
10,000 shields,
cost of the mask = 0.1 $
Cost of shield = $ 0.3
Cost of 20,000 mask = 20000 * 0.1 = $ 2000
Cost of Shield = 10000 & 0.3 = $ 3000
2000 + 3000 = $ 5000
price of all products by 30%.
Reduced Cost of mask = 0.1 - (30/100)0.1 =0.07 $
Mask could be bought = 2000/0.07 = 28,571.43
Reduced cost of Shield = 0.3 - (30/100)0.3 =0.21 $
Shield could be bought = 3000/0.21 = 14,285.71
Mask could be bought = 28,571.43 ≈ 28,571
Shield could be bought = 14,285.71 ≈ 14,286

Step-by-step explanation:
For several weeks, citizens from Victoria in Australia have been required to wear a face covering when they leave home. And while we now have a clearer path out of lockdown, it is likely masks will be around for a while.
Meanwhile, people in other states with outbreaks have been encouraged to wear masks, and some people are simply choosing to wear one as a precaution.
But some people in the community, instead of opting for a traditional mask, are instead wearing a face shield.
This might offer some degree of protection – but it is probably not as good as a mask in preventing the spread of Covid-19.
