Answer:
The equation can be used to determine the amount of money S(t) that her savings account has after t years is 
Step-by-step explanation:
A student invests $500 in a savings account
Principal = $500
Rate of interest = 4% = 0.04
We are supposed to find equation can be used to determine the amount of money S(t) that her savings account has after t years
Formula : 
Where A is the amount after t years =S(t)
t = time
r = rate of interest in decimals =0.04
P = Principal=500
Substitute the value in the formula :
So, 
Hence The equation can be used to determine the amount of money S(t) that her savings account has after t years is

Answer:
Therefore the amount in the 4% savings account = $550
Step-by-step explanation:
i) the total amount = $1500
ii) let the amount placed in the 4% interest savings account = x
iii) let the amount placed in the 5% interest savings account = y
iv) therefore fro i) we can say x + y = 1500
v) the total interest gained = $69.5
vi) therefore we can write 0.04x + 0.05y = 69.50
vii) multiplying equation vi) with 100 we get 4x + 5y = 6950
viii) Multiplying the equation in iv) by 5 we get 5x + 5y = 7500
ix) Subtracting equation in vii) from equation in viii) we get x = $550
x) Therefore the amount in the 4% savings account = $550

Answer:
Step-by-step explanation:
21.4÷4.75
- First- you have to move the decimal placement two times to the right
- Second- you have to put the number 21.4 under the dividing box
- Third- put the number 4.75 out to the left of the decimal box
- Fourth- when that's all completed you have to multiply the 475. until you get clos to the number 2140.
- Fifth- once done you have to subtract the multiplied number that you get you then subtract it from 2140
- Sixth- you keep on doing the fifth step until you get a reasonable answer
- Seventh- you write the answer down
- Eighth- there is no eighth step so you can stop reading this answer
