Answer:
The number of laps for which two swimmers have raised the same amount of money is 6 .
Step-by-step explanation:
Given as :
The amount raised by Hailey = $27 + $1.50 × each lap she swim
The amount raised by Tariana = $18 + $3 × each lap she swim
Let The number of laps after which both swimmer raised same amount = n
Now, According to question
<u>For both swimmer to raised same amount</u>
I.e The amount raised by Hailey = The amount raised by Tariana
Or, $27 + $1.50 × each lap she swim = $18 + $3 × each lap she swim
Or, $27 + $1.50 × n = $18 + $3 × n
Or, $27 - $18 = $3 n - $1.50 n
Or, 9 = 1.5 n
∴ n =
I.e n = 6
So, number of lap for same amount of both = n = 6
Hence The number of laps for which two swimmers have raised the same amount of money is 6 . Answer
Answer:
$861.09
Step-by-step explanation:
You are going to want to use the compound interest formula, which is shown below.
<em>A = total </em>
<em>P = principal amount </em>
<em>r = interest rate (decimal) </em>
<em>t = time (years) </em>
<em />
First, change 3.25% into its decimal form:
3.25% -> -> 0.0325
Next for <em>t, </em>we can use 4.25 since 4 years and 3 months is 4.25 in its decimal form. Now lets plug in the values:
Your answer is $861.09
