- Total budget: $1,200
- Fixed costs:
- Software: $249
- Research: $180
- Total fixed costs = $249 + $180 = $429
- Money remaining after fixed costs:
$1,200 – $429 = $771 - Contingency (15 % of $771):
0.15 × $771 = $115.65 - Amount left for ads:
$771 – $115.65 = $655.35
Final dollar amount available for ads: $655.35
