One more question :)
Tobias brought some money out for shopping to prepare for his backpack travelling this December. He spent 3/7 of his money on a backpack and 2/3 of the remaining amount of money on 3 identical purification bottles. He spent the rest of his money on 3 travel first aid kits. The cost of a purification bottle is $14.80 more than the cost of each first aid kit. How much money did Tobias spend on the backpack and purification bottles altogether?
