Sorry I'm not sure if I'm right just my thinking...
set the number to be x so that (5x+2)(3x-4)??
I really don’t know I’m sorry I just need to answer a question to answer mine
12 oz = 1.15
24 oz = 2.79
Let's see if 2x12oz is equal, less, or more than the 24oz.
1.15 x 2 = 2.30
2.30<2.79
The 12 oz is a better buy.
(2x+1)+(3x-5)=5x-4 you just have to try some of them out and see which ones work
