the total cost = $202.05 + $141.45 = $343.50 for 100 people
now you have to figure out 20% to add to the total. the calculation is 20% x $343.50/100% = $6870/100=$68.70
adding this to total is $343.50+ $68.70 = $412.20, now we have figure out 10% profit which is 412.20 x 10%/100%=$41.22
now add this $412.20 + $41.22 = $453.42 this is total for all of the costs
to figure out cover cost $453.42/100 = $4.50 per person
