Answer:
Step-by-step explanation:
Let x represent the amount that he paid for one hamburger.
Daniel buys lunch for his family from a food stand. He purchased one hot dog for $2.50 and 3 hamburgers. The cost of 3 hamburgers would be 3x.
If he spent a total amount of $13 on the hot dog and hamburgers, it means that
2.5 + 3x = 13
3x = 13 - 2.5 = 10.5
x = 10.5/3
x = $3.5
