Answer:
D) $247.90
Step-by-step explanation:
<h3>Understanding the equation:</h3>

y is the dependent function whereas x is the independent function.
(<em>What</em><em> </em><em>does</em><em> </em><em>this</em><em> </em><em>mean?)</em>
The values of y depend on the values of x, I.e., any change in the value of x causes a change in the value of y, meanwhile, the opposite doesn't happen.
- x represents the number of invitations
- y represents the cost to print the invitations
The cost to print the invitation depends on the number of invitations, for real.
<h3>Solution to the problem:</h3>
The question asks us to find the cost of printing 100 invitations.
Substituting x for 100:
y = (2.44 × 100) + 3.90
y = 244 + 3.90
y = 247.90
<h3>
Answer:</h3>
The value of y obtained for x = 100 is the cost of printing 100 invitations – $ 247.90
