Answer:
101.00
Step-by-step explanation:
Given:
P=principal=$1
r=rate=1%=0.01
n=number of periods=12
t=time=1
Compound Interest (A)=P(1+r/n)^nt
=$1(1+0.01/12)^12×1
=$1(1+0.00083)^12
=$1(1.00083)^12
=$1(1.0100055)
=$1.0100055
Approximately
101.00
The linear equation for his balance over time is given by:
y = 20x + 100.
- The x-intercept is of 20, which is the amount by which the balance increases each week.
- The y-intercept is of 100, which is the initial balance.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, he stats the balance with the birthday present of $100, and gets an allowance of $20 a week, hence the equation for the balance after x weeks is given by:
y = 20x + 100.
Hence:
- The x-intercept is of 20, which is the amount by which the balance increases each week.
- The y-intercept is of 100, which is the initial balance.
