Answer: The price for the product is R$5.
Step-by-step explanation: Suppose the unit price of the product is X.
T is all the money I have.
In the first option, 20 units spend all my money, so:
T = 20x
In the second option, if I buy 14 of it, I have a remaining of R$30, so:
T = 14.x + 30
To determine the unit valor:
20x = 14x + 30
20x - 14x = 30
x = ![\frac{30}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B6%7D)
x = 5
The product costs R$5.
