A) Substitution
substitute y = 5x-2 for y in the first equation and solve for x:
5x-2 = 7x-8 subtract 7x from both sides
-2x-2 = -8 now add 2 to both sides
-2x = -8 + 2 simplify
-2x = -6 divide both sides by -2
x=3
Now substitute x with 3 in either equation
y=5x-2 =5*3-2 =13
(3,13)
B) (3,13) is the point where the two lines intersect
y=mx+b is the equation of a line

Answer: $7.525
Step-by-step explanation:
A markup is an amount that is added to the cost price of an item in order to get a sell price that is used to make a profit.
Cost price= $3.50
Markup = 115% = 115/100 × 3.50
= 1.15 × 3.50
= 4.025
Selling price= Cost price + Markup
= $3.50 + $4.025
= $7.525
A customer will pay $7.525 for the item.
