Your waiter at a restaurant suggests you leave a tip of $10 on a $50 bill. What percentage is that?
Bezzdna [24]

Answer:

20%

Step-by-step explanation:

To find what percentage is $10 out of $50, we divide 10 by 50:

\frac{10}{50}=0.2

If we want to get the result in percentage form, we simply multiply it by 100%:

0.2\cdot 100\%=20\%

So a tip of $10 on a $50 bill is a tip of 20%.

Mashcka [7]

Answer:

2 %

Step-by-step explanation:

Money borrowed, Principal, P = $ 700

time of investment, T = 3 years

Total interest paid, Simple interest, S.I = $ 42

Let the rate of interest is R.

Use the formula for simple interest.

S.I. =\frac{P\times R\times T}{100}

By substituting the values

42 =\frac{700\times R\times 3}{100}

4200 = 2100 R

R = 2 %

Thus, the rate of interest is 2%.
