Given: 12 sq.ft of paper @ $1/sq.ft 4 ft of wood @ $3/ft 14 yds of string @ $2/yd
Part A: total cost for one kite =12 sq.ft of paper @ $1/sq.ft 4 ft of wood @ $3/ft 14 yds of string @ $2/yd = 12*$1 + 4*$3 + 14*$2 =$12 + $12 + $28 =$52
Part B: Total cost for four kites = 4* cost for one kite = 4*$52 =$208
