Of the two posted problems, I will solve here problem #2.
2. Joseph was tasked to buy two brands of milk. The price of brand A per box is P100.00
and the price of brand B is P120.00. His budget is 600. He is to buy twice as many cans
of brand A
brand B. How many boxes of each brand will he purchase?
S O L U T I O N
Let x be the number of cans brand B. Then the number of cans brand A is 2x.
Write the inequality for the budget
100*(2x) + 120*x <= 600.
Simplify and get the solution for x
200x + 120x <= 600,
320x <= 600
x <=
= 1.875.
Since x must be non-negative integer, we have two possible values for x: 0 and 1.
The '0' is degenerated solution, and only meaningful solution is
"two cans of brand A and one can of brand B". ANSWER
Solved.

In the future, do not pack more than one problem per post.
It is the RULE and the POLICY of this forum.
