Answer:
The profit for January is $57,200.
Step-by-step explanation:
The total profit for the two months would be the result of adding up the profit in January plus the profit in February:
Total profits=Profit in January+Profit in February
Also, you can say that profits in January can be represented by x and you know that the profit for a company in February was 15% higher than it was in January which can be expressed as: 1.15x. Moreover, you know that the total profit for the two months was $122,980. Now, you can replace the values on the formula:
122,980=x+1.15x
Now, you can solve for x:
122,980=2.15x
x=122,980/2.15
x=57,200
According to this, the answer is that the profit for January is $57,200.
