Question

a graphic designer offers logo designs for a flat fee of $200, plus $50 per revision. which equation represents the total cost t after r revisions?
a. t = 200 + 50r
b. t = 250r
c. t = 200r + 50
d. t = 50 - 200r

a mobile app subscription costs $1.99 per month after a one - time setup fee of $0.99. write the total cost c equation for n months.
a. c = 0.99 + 1.99n
b. c = 1.99 + 0.99n
c. c = 0.99n - 1.99
d. c = 2.98n

Explanation:

First Question Step1: Identify fixed and variable costs

Fixed cost = $200, variable cost = $50 per revision

First Question Step2: Form total cost equation

Total cost \( T = \text{fixed cost} + (\text{cost per revision} \times \text{number of revisions}) = 200 + 50r \)

Second Question Step1: Identify fixed and variable costs

Fixed setup fee = $0.99, variable cost = $1.99 per month

Second Question Step2: Form total cost equation

Total cost \( C = \text{fixed fee} + (\text{cost per month} \times \text{number of months}) = 0.99 + 1.99n \)

Answer:

A. \( T = 200 + 50r \)
A. \( C = 0.99 + 1.99n \)
