Step-by-step explanation:
The equation that would help determine the cost of 777 markers is option B, 777x = 7.04.
To find the cost of 777 markers, we can set up a proportion using the given information:
x markers cost $7.04
44 markers cost $7.04
Using the proportion, we can solve for x to find the cost of 777 markers:
44/7.04 = 777/x
Simplifying the equation further, we get 777x = 7.04.
