*i mark brainliest* me on this question, explaining it, so i can understand this topic. you.

Answer d, because the equation is stating 3= $4.41, we are trying to figure out how much 4 cost

So d is correct as if u wanted to find out how much one thing cost u need to divide the number of the thing by its cost .An example is 20dollars for 4 apples. so 20/4=5 dollars for each apple. 

This equation shows how much 3 erasers cost, which in this case its 4.41. the equation equals to 4/x as the cost of 1 eraser is the same. so if u wanted to solve this equation, u can use the cross method to multiply it so 

3x=4.41*4
3x=17.64
x=5.88
