<span>I can solve for x and y A) 2x - 4y = 12
A) 2x = 4y + 12 A) x = 2y + 6 Substituting into B B) 3* (2y +6) - 5y = 20
B) 6y + 18 -5y = 20 B) y = 2 B) x = 10
The cost on startup is $10 and each painted rock cost around $0.75 to make. A store pays startup cost and buy painted rocks for $0.75 each there no profit because the cost price and selling price is the same.
