Answer:
New balance = 3640
Step-by-step explanation:
Given the following data;
Interest rate = 4% = 4/100 = 0.04
Principal = 3500
To find the new balance;
First of all, we would find the amount at the interest rate;
New amount = interest rate * principal
New amount = 0.04 * 3500
New amount = 140
Now, to find the new balance;
New balance = principal + new amount
New balance = 3500 + 140
New balance = 3640
Answer: 1.2x
Step-by-step explanation:
Profit = Selling price - Cost
She bought the stock at a cost of x dollars
Her profit was 20% of that, which is 0.2x dollars
Selling price = Profit + Cost = x + 0.2x = 1.2x
30 times
150/5=30
Hope this helps :)
Answer:
C
Step-by-step explanation:
Find the polar coordinates in the usual way, then negate r and add 180° to θ.
You know that
... r = √(x² + y²)
... θ = arctan(y/x) . . . . . taking quadrant into account
The coordinates (r, θ) and (-r, θ+180°) specify the same point.
