Assume that the number of apples is x and the number of oranges is y.
For the first given, we know that each apple costs $0.24 and each orange costs $0.8, therefore:
amount paid for apples = 0.24x and amount paid for oranges = 0.8y
we also know that the total amount spent is $12, therefore the first equation is as follows:
0.24x + 0.8y = 12
For the second given, we know that the total number of fruit bought is 20, therefore, the second equation is:
x + y = 20
You can easily graph these two functions and find a possible combination from the graph (the correct combination would be the intersection between the two lines).
Answer:
The sales is Rs. 12150.
Step-by-step explanation:
Given : You own a pet supply store, and the total sales in your trading area equal 27,000. Your market share is 45%.
To find : What were your sales ?
Solution :
Total sales = 27,000
Market share = 45%
Sales is given by,
Sales is 45% of total sale.
So, 

Therefore, the sales is Rs. 12150.
For this case, the first thing we must do is define variables.
We have then:
t: number of hours
F (t): total charge
We write the function that models the problem:
Where,
b: represents an initial fee.
We must find the value of b.
For this, we use the following data:
Her total fee for a 4-hour job, for instance, is $ 32.
We have then:
From here, we clear the value of b:
Then, the function that models the problem is:
Answer:
the function's formula is:
