That’s the answer because I couldn’t type it out! Hope it helped!
Let F be the father's current age, and E be Evie's current age.
F = E + 36 this is the current relation between the ages
F + 3 = 5(E + 3) this the relationship in 3 year (hence the + 3)
Then solve by substituting one equation into another:
(E + 36) + 3 = 5(E + 3)
E + 39 = 5E + 15
24 = 4E
6 = E
Evie's current age is 6.
Answer:

Step-by-step explanation:
1. You must clear the absolute value bars.
2. You have two cases: a positive case and a negative case.
3. First, you can solve the positive case as following:

4. Now, you must solve thie negative case as you can see below:

5. Therefore, the answer is:

Amount= Deposit or initial amount ( 1+ percent increase) ^period of time
So Amount= 50(1+0.1)^3
= 50(1.1)^3
= 50(1.331)
=66.55
So she will have $66.55 in 3 years.
