Okay, so this is a simple interest calculation, the formula for this is:
A = P(1 + rt) P = Principal, r = interest rate, and t = period of time
Convert time period to decimal:
1/4 = .25
2 3/4 = 2.75
Convert interest rates to decimals.
10.5% = .105
5.9% = .059
Now plug in the variables into the formula and calculate.
A = 7,000(1 + (.105 * .25))
= 7,000(1.02625)
= 7,183.75
A = 1,900(1 + (.059 * 2.75))
= 1,900(1.16225)
= 2,208.275
Answer:
Ana wins by about 2.5 minutes.
Step-by-step explanation:
Bea:
10,000-600=9,400
9,400/200= 47minutes to finish
Ana:
10,000/225=44.44minutes to finish

y intercept: (0, -39)
slope: 13/5
Step-by-step explanation:
The attachments below is the slopes and x and y intercept
Hope this helps (:
First, you find 5% of $50.
To do this, you times 50 by 0.05. This is because if you were to turn 5% into a decimal, with 1.0 being 100%, 5% would become 0.05.
50 x 0.05 = 2.5
After you have the amount, simply add it onto the original $50.
50 + 2.5 = 52.5
The new price is $52.5.
