Alright, lets get started.
Suppose previously I was selling product per week = x
As per question, I have decreased my average number of product by 15 %
Means I have decreased number of product by : x * 15 % = x * 0.15 = 0.15 x
So, the new average product = x - 0.15 x = 0.85 x
As per given question, the new average product = 21.25
0.85 x = 21.25
Dividing by 0.85 in both sides
0.85 x / 0.85 = 21.25 / 0.85
x = 25
Hence it means, 25 products were selling previuosly. : Answer
Hope it will work :)
The amount of products previously sold per week was 25 products.
What are word problems?
Word problems in mathematics involve the interpretation of words by using mathematical variables and the use of arithmetic operations.
From the information given:
- Let x be the original number of products sold at
- Now, the decrease in the actual number of products sold by 15% = 0.15x
Now, the actual products is:
x - 0.15x = 0.85x
However, if the trader now sells an average of 21.25 products in a week;
Then;
0.85x = 21.25
x = 21.25/0.85
x = 25 products
