Question

standard form sam ordered two hamburgers and three hot dogs from the concession stand at the baseball game. his bill came to $19.05. If hamburgers cost $5.25 each, write and solve a linear equation to find the cost of each hot dog.

Answer 1

Let a = hamburgers and b = Hot dogs

10.50 + 3b = 19.05

b = 2.85

Explanation:

Let a = hamburgers and b = Hot dogs

2a and 3b = 19.05

We're told that hamburgers (a) are 5.25 so now we can change the equation to

2(5.25) + 3b = 19.05

10.50 + 3b = 19.05

3b = 8.55

b = 2.85
