Question

Someone answer this question for me .

Answer 1

Answer:

Let x be the number of hours worked in each case

Let m be the amount of dollars each of them make working in their respective jobs

Let b be the amount each of them has saved before working.

The equation that represents both cases is a line

y = m*x +b    (slope intercept form)

Maryann

y1 = 6($/hour) *x + $9

Carlos

y2 = 9($/hour) *x + $3

The slopes represent the amount of dollars each of them can make in an hour

We are basically asked to find the solution of the system of equations

(amount of hours = x, and amount  of $ obtained = y)

Using a graphing tool, we can easily find the intersection of both graphs, which represent the solution for the problem.

The solution is

Hours of work = x = 2

Amount  of $ obtained = y = 21
