12j + 12 + 3j or 15j + 12. This is because if you use Distributive Property to distribute the 3, then you multiply 3 by all the number inside the parentheses. I have two expressions because once you get get the answer after you use the property, then you can combine like terms, such as 12j and 3j which is 15j. Hope this helps!

Answer:
He gave 8.57 % of his money for his cousin.
Step-by-step explanation:
In order to calculate the percent that Pedro gave to his cousin, we first need to calculate his total amount, which is given by "x". This is given by:
x = 15 + (x - 15)/5 + 128
x = 15 + x/5 - 3 + 128
x = x/5 + 140
x - x/5 = 140
(5*x - x)/5 = 140
4*x = 700
x = 175
He had originally $175 and gave $15 to his cousing, therefore we can use a rule of three to calculate the percent that he gave to his cousin:
$175 -> 100%
$15 -> y%
175*y = 1500
y = 1500 / 175
y = 8.57 %
