Answer 5

@hayhay12345

Sorry, I wasn't online.

The answer to the first question is august ; You have to use the least squares method in order to determine the equations for revenue and expense.

Alternatively draw a graph for the values of both revenue and expense (separately!) and draw a line between the points so that you end up with a graph that fits the data.

The equation for revenue will be: 4100m + 300 (where m = month)

The equation for expense will be: 1900m + 19900

if revenue and expense are to be equal, their equations have to be dependent.

therefore subtracting the two equations, you get: 2200m - 19600

m = 19600/2200 = 8.9

August is the 8th month, therefore revenue and expense will be equal at the end of august.




Your second answer is correct.
