Question

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?

Answer 1

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 <===
