Mathematics
1 answer:
Arturiano [62]3 years ago
5 0
Formula for amount, A, in Compound Interest:

A = P(1 + r)ⁿ

Where P = Principal = $800,  r = rate per year = 7% = 0.07, n = number of years = 4

A =  P(1 + r)ⁿ

A =  800(1 + 0.07)⁴

A = 800(1.07)⁴             Use your calculator

A ≈   1048.6368

A ≈ $1048.64

I hope this helped.

Adelaide paid $35 for a manicure and gave the manicurist a 20% tip How much money did Adelaide give her manicurist
seropon [69]
<span><u><em>The correct answer is:</em></u>
$42.

<u><em>Explanation:</em></u>
The best way to find a total bill including tip (or tax if that is what you are looking for - it is found the same way), is to multiply the original total by 1 + the percentage of the tip.

Since the percentage is 20%, we add 0.20 to 1 to get 1.20.
Now we multiply that by the original cost to get the final answer.
1.20*35 = 42</span>
