Decimal division: problem solving
First we solve a multi-step word problem that could be from real life: if you know the total of 7 bottles of water and 15 blueberry muffins (Mathy's favorite), and you know the cost of one bottle of water, then how do you find the cost of one muffin? The solution involves several operations with decimals.
Secondly, I present a multi-step calculation and the task is to find a situation that fits it. I suggest one, Mathy has another, and maybe you can find a third. :)
