Answer:
Let n represent the number of months after Tina would save the same amount using either option.
400 + 30n = 100 + 50n
400 + 30n − 30n = 100 + 50n − 30n Subtraction Property of Equality
400 = 100 + 20n Combine like terms.
400 − 100=100 + 20n − 100 Subtraction Property of Equality
300 =20n
300
20
=
20n
20
15 months=n
After 15 months, Tina will save the same amount using either option.
400 + 30(15)=100 + 50(15)
400 + 450=100 + 750
850 = 850
After 15 months, Tina will save $850 with either option.

Answer:
Step-by-step explanation:
The amount formula in compound interest is:
where:
P = principal amount
r = annual interest
n = number of compounding periods
t = number of years
We already know that:
P = $3000
t = 2
n = 365
Then,
The first option is the correct answer
Answer:
Step-by-step explanation:
The x-coordinate is negative, so the point is to the left of the y-axis.
The y-coordinate is positive, so the point is above the x-axis.
