Answer:
She spent 2 and a half hours doing extra work.
The answer is $412.
Let's first calculate simple interest. Simple interest (I) can be expressed as:
I = P * r * t
P - principal
r - rate
t - time period
It is given:
I = ?
P = $400
r = 3% = 0.03
t = 1 year
Therefore:
I = P * r * t = 400 * 0.03 * 1 = 12
The total amount Kate will repay is the principal amount (P) plus 3% simple interest (I):
P + I = 400 + 12 = $412
Answer:
Distributive?
Step-by-step explanation:
The way the problem is laid out confuses me but if it is the problem that you laid out, it should be Distributive.
