Answer:

See below

Step-by-step explanation:

Let the number of Payday be p and Baby Ruth be b

<u>Then sub of the candy bars:</u>

  • p + b = 220
  • Payday candy bars worth ⇒ $2p
  • Baby Ruth candy bars worth ⇒ $3b
  • Total ⇒ $600

1. <u>Required equations:</u>

  • p + b = 220
  • 2p + 3b = 600

2. <u>Solving by substitution:</u>

p = 220 - b, consider it in the second equation

  • 2(220 - b) + 3b = 600
  • 660 - 2b + 3b = 600
  • 660 + b = 600
  • b = 660 - 600
  • b = 60
