Step-by-step explanation:
Let us set the variables for the quantities as follows:
Let number of oranges = o
Let number of grapefruits = g
Cost of unit orange = 0.75
Cost of unit grapefruit = a
Total number of fruits (oranges + grapefruit) = f
Total amount paid = t
Now, we use these variables to find the required solution.
Since the total number of fruits sold is the sum of oranges and grapefruits, therefore
o + g = f       ………………….. (1)
The total amount paid is the sum of total cost of oranges as well as grapefruits, therefore
0.75o + ag = t   ……………….. (2)
Now to find the solution of the given problem, one needs to specify the values of a, f, t
Once you have those equations, you solve the system of equations (1) and (2) using Substitution and Elimination Methods to solve for the variables o and g.
