Answer :
you add all the shirts pants etc together...which is 12+29+49 then you times it by 5 because there are 5 members in the group, this will leave you with the total cost of the bands outfits! you total should be $450 in the end
If you add the cost of the uniforms up to get to get 90 (12+29+49) that gets you the cost of a uniform for one person. If you take 90 and multiply it by 5 (since there are 5 members) you get $450 as a total cost.
