Bradley Cole · Answer 1

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).
