Minerva starts a savings account with $50. The interest on the account balance is compounded annually. The graph below shows the
rodikova [14]

We can set up this equation using this formula:

a = p(1 + r/n)^nt

p = starting amount.

r = interest.

n = number of times it's compounded in a year

t = years

We'd set it up like this:

a = 50(1 + ?/1)^1(12)

Because we're missing the amount of interest, it would be impossible to tell what the amount would be after 12 years.

Answer:

Gabe worked 65, Abe worked 62 and Babe worked 69.

Step-by-step explanation:

Let Gabe = x

Therefore, Abe worked: x-3 and Babe worked x+4

So,

x+(x-3)+(x+4)=196

3*x+1=196

3*x=195

x=65

Then,

x-3= 62

x+4=69
