Answer:
3.5x+22.5/x+10= 3
Explanation:
Given,
The number of roses = x,
Price of each rose = $ 3.50,
So, the total price of roses = 3.5x dollars,
Now, the number of carnations = 10,
The cost of each carnation = $2.25,
So, the total cost of all carnations = 10 × 2.25 = $ 22.5,
Thus, the total cost of a bouquet of flowers = ( 3.5x + 22.5 ) dollars,
Also, the total numbers of flower = x + 10,
Hence, the average cost flowers =
According to the question,
The average cost of flowers = $ 3.00
Which is the required equation.
