Question

Rachel can buy licorice sticks for $0.75 and cherry candies for $0.50 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? (Note: x ≥ 0, y ≥ 0, and x and y take only integer values.)
A)20
B)25
C)50
D)100

Answer 1

Well you just have to provide the number of each item she wishes to buy. So 0.75x would be 0.75(0) which would equal 0. Then you have 0.5y=25. What would you do then?

Answer 2

divide 25 by 0.5 right?

Answer 3

yep!

Answer 4

thank you
