Question:

An Internet business charges a flat rate of $6.50 for shipping. If x represents the cost of the items purchased and y represents the total cost with shipping, which equation best represents the relationship between x and y?

Answer:

y = 6.5 + x represents the relationship between x and y

Solution:

Given that,

An internet charges a flat rate of $6.50 for shipping

Let "x" be the cost of items purchased

Let "y" be the total cost with shipping

Therefore,

Total cost with shipping = flat rate of 6.50 + cost of items purchased

Thus, we get,

y = 6.50 + x

y = 6.5 + x

Thus the above equation represents the relationship between x and y
