The chemistry café cook has a loaf which had 33 slices and a package of cheese that has 15 slices. he is making sandwiches that have 2 pieces of both breed and cheese. how many sandwiches can he make?

Explanation:

so

2 breads + 2 cheeses ⇒ 1 sandwich

if we use two slices of bread each time how many sandwich can we make with 33 slices

33/2 =16.5 sandwiches

if we use two pieces of cheese in each sandwiches how many sandwiches can we make with 15 slices ?

15/2 =7.5 sandwiches

the cheese her will run out first and we would have excess bread

so we would only be able to make 7.5 sandwiches without running out of ant ingredient :)

good one: produce hormones that plants grow.

bad one: the problem with organic matter is that while plant nutrients are needed for crop growth, they can also stimulate excessive growth of the wrong plants – mainly, algae.
