Answer: 387.93 units
Step-by-step explanation:
You have the following information given in the problem above:
- The sales had dropped 33% from one quarter to the next.
- The owner sold 579 units in the first quarter.
Thefore, to calculate the number of units she sold in the next quarter (which you can call x), you must can apply the following proccedure:
Then the answer is the following:
Equation is (x+2)^2 - x^2 = 7676
solve the equation by first opening the bracket of (x+2)^2 by A^2 + 2AB +C^2
you'll end up with 4x + 4 = 7672
thus x = 1918 and the next number is 1920.
