PLEASE HELP!! I tried everything. I got answers $18.20 & $20 Chris Nazarro had total travel expenses of $872. His transportation cost was $136. The hotel cost was $210 and business materials cost $500. If his lunch cost 30% of his dinner, how much was dinner to the nearest cent?

Let x be the cost of dinner. Then 0.3x is the cost of lunch. Add up all the costs and set them equal to 872 136 + 210 + 500 + x + 0.3x = 872

846+ x + 0.3x=872

x+0.3x=26
