This problem is the easiest to use equations, and I'm afraid you didn't learn equations last semester, so I'll use unary equations to solve it!

If the bottle is X-ray and the bottom is (150-X), then

Analysis: Now X-rays are used to make bottles, and (150-X) pieces are used to make bottle bottoms. 1 pieces of aluminum can be used to make 16 bottle bottoms, so * * * can be made.

Bottle body 16X bottle bottom 43 (150-x)

A bottle body and two bottle bottoms can be matched into a set: it can be understood that the number ratio of bottle body and bottle bottom is 1: 2, and the equation is:

16X:43( 150—X)= 1:2

Solve equation X=86

Namely: 86 aluminum plates on the bottle body and 64 aluminum plates on the bottle bottom.
