You and a friend go to a farmers' market. You spend $13 on fruit. Then you and your friend each buy the same number of tomato plants for $4 each. a) Write a system of linear equations that represents this situation b) Will you and your friend spend the same amount of money? Explain.

Answer: a) y = 4x + 13

y = amount we both spent

x = number of tomato plants we both bought

$13 is the amount I spent on fruits

b) No, we won't spend the same amount

Step-by-step explanation:

Amount spent on tomato plants

= $4 * x tomato plants

However, I already spent $13 on fruit ... It will be added to the amount spent on tomato plants

y = 4x + 13 (where y is the total amount spent by us both)

Obviously, I spent more than he did
