Hey i need help, i dont know the working outs.
a shopkeeper sold his entire stock of shirts and ties in a sale for $10 000. The shirts were priced at 3 for $100 and the ties $20 each. if he had sold only half the shirts and two-thirds of the ties he would have received $6000. how many of each did he sell in the sale?
answer- 120 shirts and 300 ties
shirts -x ties - y
x+y= 10 000
if he had sold only half the shirts and two-thirds of the ties he would have received $6000 ?
shirts x/2 ties 2y/3 ?? so x/2 + 2y/3= 6000 ??
