but you can buy licorice for $.75 sticks and Cherry candies $.50 and has a budget of $25. if her expenses are represented by the equation 0.75x + 0.5y=25. where x is the number of licorice sticks and y is the number of cherry candies, how many cherry candies can she buy if she wishes to spend the entire $25 on cherry candies?
0.75x + 0.5y = 25.....she wishes to spend it all on cherry candies (y)..so we sub in 0 for x. 0.75(0) + 0.5y = 25 0 + 0.5y = 25 0.5y = 25 y = 25/0.5 y = 50 <===
