Answer:
2 kilogram bag.
Step-by-step explanation:
To figure this out, we need to divide the price by the amount of kilograms. Lets start with the 3 kilo bag. Divide 42 by 3, let y equal the price per kilo
42/3=y
Divide
14=y
Now lets do the same with the 2 kilo bag. Divide 26 by 2. Let x be this number.
26/2=x
divide
13=x
The 2 kilo bag is better as its 13 pesos per kilo compared to the 3 kilo bag's 14 pesos per kilogram.
Hi well you didn’t tell me weather your adding them, subtracting, dividing, or multiplying. So here is the answer for all 4 of them. Adding them you get 1261.8, subtracting then you get -43.8, multiplying them you get 397555.2, and dividing them you get 1015/1088. If you just need the answer for each one (5.8x105) is 609 and (6.4x102) is 652.8. Hopefully I helped in some type of way. Have a good night :)
