• Solving quadratic equations

Khalil buys four cans of soup and three loaves of bread for $11.67. What equation represents this purchase?

• 4C + 3B = 11.67

• 3C + 4B = 11.67

• 4C + 3B = 12.89

• 3C + 4B = 12.89

Rhonda buys eight cans of soup and one loaf of bread for $12.89. Which equation represents her purchase?

• C + 8B = 11.67

• B + 8C = 11.67
