EXPLANATION
Ginny has $10,000 in a savings account.
The interest is 4% simple interest.
We want to calculate Ginny's total account balance after 20 years.
To do this, we will first caluclate the interest and then we will add it to the initial balance.
To calculate Simple Interest, we use:

P = principal = $10000
R = rate = 4%
T = time = 20 years
Therefore:

Therefore, her account balance after 20 years is:
Amount = $10000 + $8000 = $18,000
Answer:
Y = 28
Step-by-step explanation:
Y=16 + 12 = 24
Therefore the y scored 24 points
When multiplying by a number that is 1 with 0's on the end, you move the decimal to the right by how many zeros there are.
Because 10,000 has 5 0's, we move the decimal 5 places to the right.
8.88 => 88800
