Target is 40% mushrooms. His current ingredients would yield 19%2F%2819%2B12%29=0.6129 fraction as mushrooms. We can use the expression and adjust the target to 0.40 and apply a variable to SUBTRACT from the mushroom quantity of 19.

Let's say, Andrew would use 19-w ounces of mushrooms.
%2819-w%29%2F%28%2819-w%29%2B12%29=0.40
Solve for w, and then compute 19-w.

You may find another way to solve this problem. My solution described is not necessarily the only way.

Andrew wants to make a salad using mushrooms and lettuce. the salad needs to have 40 percent mushrooms. He has 19 ounces mushrooms and 12 ounces of lettuce. how many ounces of the mushrooms should be used if He wants to use all of the lettuce

Mushroom + mushroom = mushroom

Let quantity of mushrooms be M

M + 0(12) = .4(M + 12)

M = .4m + 4.8

M - .4M = 4.8

.6M = 4.8

M, or quantity of mushrooms to be used = 4.8%2F.6, or highlight_green%288%29 oz.

You can do the check!!
