Jill and Jack are getting vegetables from the Farmer's Market. Jill buys 12 carrots and 8 tomatoes for $34. Jack buys 10 carrots and 7 tomatoes for $29. How much does each carrot and each tomato cost?

Let the cost of carrots be c and the cost of tomatoes be t. Since the total cost is price times quantity, We're given two equations:
  1. 12c + 8t = 34 <-- Jill
  2. 10c + 7t = 29 <-- Jack
We have a system of equations. We can solve this one of three ways:
  1. Substitution Method
  2. Elimination Method
  3. Cramer's Rule
No matter what method we choose, we get:
  • t = 2
  • c = 1.5
