Let first find the purchase price (cost) of 2 pair of pants, 3 dress shirts, and 1 suit jacket.
2 pants = \(74*2=148\)
3 dress shirts = \(48*3=144\)
1 suit jacket = \(325*1=325\)
Summing all these, we have \(148+144+325=617\)
Harold marks up 27% of his cost. So we add 27% of 617 to 617.
\(617+(0.27)(617)=783.59\)
Hence, Harold charges $783.59 to his customer who will buy 2 pants, 3 shirts, and 1 suit jacket.
