Answer:
$117
Step-by-step explanation:
$90*10= $9
1 year is $9 interest, which is increase.
$9*3=$27
So than you add $27 and $90 and get $117
I don't speak Spanish but I think that this is what you meant:
80 * 2/5 = 32
so 2/5 of 80 % is 32 % (80/5 * 2)

since it is exactly in the halfway between
Answer:
5v + 32y = 350
Step-by-step explanation:
Let, the year counting starts in 2011 and represented by y.
So, the share of ABC stock value was $70 at y = 0. And in the year 2016 i.e. y = (2016 - 2011) = 5, the share worth $38.
If there is a linear relationship between the number of years since 2011 i.e. y and the value of the share of ABC stock i.e. v, then we can write the equation of this situation as
⇒ 5v - 350 = - 32y
⇒ 5v + 32y = 350 (Answer)
