<em><u>Question:</u></em>
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?
<em><u>Answer:</u></em>
y = 6.5 + x represents the relationship between x and y
<em><u>Solution:</u></em>
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

Step-by-step explanation:

Since ∠EBA = 90° then ∠ABD = 90° ( straight angle ) and
∠ABC + ∠CBD = ∠ABD, that is
2x + 3x - 10 = 90, simplifying
5x - 10 = 90 ( add 10 to both sides )
5x = 100 ( divide both sides by 5 )
x = 20, thus
∠ABC = 2x = 2 × 20 = 40°
∠CBD = 3x - 10 = (3 × 20) - 10 = 60 - 10 = 50°
(6)
4x - 18 = 3x + 7 ( vertical angles are congruent )
Subtract 3x from both sides
x - 18 = 7 ( add 18 to both sides )
x = 25
7y = 5y + 28 ( vertical angles are congruent )
Subtract 5y from both sides
2y = 28 ( divide both sides by 2 )
y = 14
