It is not possible to have the total earnings of $51,470 for February.
Explanation of Solution
Given information:
The sales of January and February are given as follows:
Sale month | No. of computers sold | No. of printers sold | Total sale amount |
January | 24 | 40 | $38736 |
February | 30 | 50 |
Condition: Assume that prices are constant for January and February.
Calculation:
Let the number of computer and printer be c and p respectively.
According to the condition, the equation for January will be as follows:
