D is under multiplication
Solve systems of equations by graphing. A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system.

3 hours = 26.25
---------------------------------
Find wages for 1 hour :
---------------------------------
1 hour = 26.25 ÷ 3 = 8.75
---------------------------------
Find wages for 8 hours :
---------------------------------
8 hours = 8.75 x 8 = $70
---------------------------------
Find wages for a week :
---------------------------------
$70 x 7 = $350
---------------------------------

---------------------------------
2 hours = $15
---------------------------------
Find 1 hour :
---------------------------------
1 hour = $15 ÷ 2 = $7.50
---------------------------------
Find 8 hours :
---------------------------------
8 hours = $7.50 x 8 = $60
---------------------------------
Find 1 week :
---------------------------------
1 week = $60 x 5 = $300
---------------------------------
Define x :
---------------------------------
Let x be the number of weeks needed
---------------------------------
Construct equation :
---------------------------------
350x = 300x + 1000
---------------------------------
Solve for x :
---------------------------------
350x = 300x + 1000
---------------------------------
Take away 300x from both sides :
---------------------------------
50x = 1000
---------------------------------
Divide by 50 :
---------------------------------
x = 20
------------------------------------------------------------------
Answer: It will take 20 weeks.
