Matthew and Karen are shopping for vegetables to make soup. Karen buys 1 onion and 2 carrots. Her total cost (before tax) is $1.30. Matt buys 3 onions and 6 carrots. His total cost before tax is $3.90. Create two equations that you could use to find the cost of a single onion and a single carrot. Use the variable n to represent 1 onion and the variable c to represent 1 carrot. Then for the situation, find the cost of a single carrot and the cost of a single onion.
