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 = 250r
b. t = 200r + 50
c. t = 200 + 50r
d. t = 50 - 200r

the total cost for printing x copies of a book is $200 plus $2.50 per copy. which equation represents the total cost (c)?
a. c = 200 × 2.50
b. c = 200x + 2.50
c. c = 200 - 2.50x
d. c = 200 + 2.50x

a taxi company charges a $5 initial fee and $2 per mile. which equation models the total cost c for x miles?
a. c = 5x + 2

Explanation:

First question

Total cost = flat fee + cost per revision × number of revisions. Flat fee is $200, cost per revision is $50. So \( T = 200 + 50r \).

Second question

Total cost = initial cost + cost per copy × number of copies. Initial cost is $200, cost per copy is $2.50. So \( C = 200 + 2.50x \).

Third question

Total cost = initial fee + cost per mile × number of miles. Initial fee is $5, cost per mile is $2. So the equation should be \( C = 5 + 2x \). (Assuming the missing option matches this.)

Answer:

First question: c. \( T = 200 + 50r \)
Second question: d. \( C = 200 + 2.50x \)
Third question: (Note: The third question's options are incomplete in the provided text, but based on the pattern, the correct equation would be \( C = 5 + 2x \) if that option exists.)
