Step-by-step explanation:
Answer:
Graph is attached below
Step-by-step explanation:
You first need to plot any two points on the coordinate plane(you can also do more than two points to make it more accurate). Then, using a ruler connect the points and extend the line outwards.
$40+$35=$75
75/100*8.75=6.5625
6.5625+75=81.5625
approximately equal to $81.56
X= fancy, y= plain
x+y= 7
28x+ 15y=131
solve by substitution
