Answer 1

Explanation:

Cost to run one week

• $35 [first 4 lines] + $5.25 x 11 [15 - 4 = 11 remaining lines]
• $35 + $57.75
• $92.75

Cost to run four weeks

• Cost of one week x 4
• $92.75 x 4
• $368 + $3
• $371

Answer 2

• a) $92.75, b) $371

Explanation:

Let the cost be A.

a) Cost to run ad for one week:

• A = 35 + 5.25 (15 - 4) = 35 + 5.25*11 = 92.75

b) Cost to run ad for four weeks:

• 4A = 4*92.75 = 371
