Ax+bx−c=0
Step 1: Add c to both sides.
ax+bx−c+c=0+c
ax+bx=c
Step 2: Factor out variable x.
x(a+b)=c
Step 3: Divide both sides by a+b.
x(a+b)a+b=ca+b
x=ca+b
If my math is right the it’s 21.13

Answer:
$4.95 + $3.99b = c
I can't make a graph but start at 4.95 on the graph and move up 3.99 every time you go to the right once
Students total 43430
5742 students more
43430-5742=37688
37688/2 = 18844
