Based on the information given, the simple interest rate that will be earned will be 13.6%.
- Principal = $5250
- Simple Interest = $6500- $5250 = $1250
- Time = 21 months = 1.75 years.
Simple Interest = PRT / 100
1250 = (5250 × 1.75 × R) / 100
Cross multiply
125000 = 9187.5R
R = 125000 / 9187.5
R = 13.6%

Answer: I am pretty sure its 15 for Bs age!
Step-by-step explanation: All I did is find the equivalent ratio!
5 x 3 is 15 and 6 x 3 is 18
28 + 18.25x = 161 -15x (here, x stands for every week this addition or withdrawal happens)
So:
28+18.25x = 161 - 15x
18.25x = 161 - 28 - 15x
18.25x = 133 - 15x
18.25x + 15x = 133
33.25x = 133
x = 133/33.25
x = 4
So, they will have the same balance in 4 weeks.
Answer:
(1-33/100)x and 0.67x
Step-by-step explanation:
33% is 33 out of 100, or 33/100. Since the new recipe has 33%, or 33/100, less sodium, this means we take x, the amount in the old soup, and subtract 33/100 from it:
1 - 33/100 would represent the percent of sodium remaining, and x is the original amount, giving us (1-33/100)x.
If we write this percent as a decimal, we get 0.33. Taking this away from 100%, which is written in decimal form as 1, we get
1 - 0.33 = 0.67
Now we multiply this by the original amount of sodium, x:
0.67x
