THE ANSWER IS B $115 plz mark me brainliest i want points :’)
Answer:
The answer is 10 12/85 Hope you pass!
270=2b + a
420=2a + 3c (you have to use trial and error for this)
B = 120
A = 30
C = 120
Just to check
270 = (2x120) + 30
420 = (2x30) + (3x120)
I think the answers are Number 1 -2. Number 2. is 2. Number 3. is 4. Number. 4 is 6. And number 5. is 12. I hope this helps :)
The example of real life situations is: The cost of 30 green apples is €60
Rox wants to buy only 5 apples, how much will they cost her?
Cost of 30 green apples is €60.
Cost of 1 green apple = €60/30 = €2
(Using the concept of division of rational numbers)
Now, cost for 5 green apples =5 * €2 = €10
