A company bought $400000 worth of equipment from a retailer business, but pieces of equipment worth 40% of the total number were faulty. If they returned the faulty pieces of equipment to the seller, calculate the total amount of money spent on functioning pieces of equipment.

How much were the faulty pieces of equipment bought for? ** If 40% worth of the pieces of equipment bought were faulty and were returned, the amount of money they were bought for is 40/100*$400000 = $<<40/100*400000=160000>>160000
How much was the functioning equipment bought for? ** Since the faulty pieces of equipment were worth $400000, the functioning equipment was worth $400000-$160000 = $<<400000-160000=240000>>240000
