Wrenches cost 50 per carton and hammers 150 per carton. If an order comes in for a total of 60 cartons for 5k How many cartons of hammers were ordered and how many cartons of wrenches were ordered?

40 cartons of wrenches 20 cartons of hammers

Step-by-step explanation:

If all 60 cartons were wrenches, the total would be 50·60 = 3k. The total was 2k more than that. Each carton of hammers (instead of wrenches) adds 100 to the total, so there are 2000/100 = 20 cartons of hammers. The remaining 40 cartons are wrenches.
