<em>Karl Schwartz'</em>s lunch cost $25

<em>Karl Schwartz</em> total travel expenses comprises of <em>transportation cost, lodging cost, dinner cost, lunch and additional cost.</em>

In order to determine the cost of lunch, the first step is to determine the total cost of dinner and lunch.

Cost of lunch and dinner = total travelling expenses - sum of costs

$643 - ($290 + $198 +$80)

$643 - $568

Cost of lunch and dinner = $75

Let x represent the cost of lunch

cost of dinner = 2x

2x +x = 75

3x = 75

x = $25
