Iam giving you 50 points to answer this: the cost of one hamburger and two large sodas is $5.40.the cost of three hamburgers and one large soda is $8.70. what is the cost of one hamburger?

2.40

5.40-2.40= 3 (price of 2 sodas)

8.70 - 7.20 = 1.5 (price of 1 soda)

The soda prices match up so a hamburger is 2.40
