Answer:

The rainfall on Saturday was of 60 mm.

Step-by-step explanation:

Average rainfall:

The average rainfall is given by the total rainfall divided by the number of days(7). So

If the records of daily rainfall from Sunday to Friday were 45 mm, 22 mm, 28 mm, 36 mm, 30 mm and 24 mm

On Saturday it was of x mm. So

35 = \frac{45 + 22 + 28 + 36 + 30 + 24 + x}{7}

185 + x = 245

x = 245 - 185

x = 60

The rainfall on Saturday was of 60 mm.

Given that,

Michael is leaving a 15% tip for his waitress.

To find,

What percent of the  original price will he pay.

Solution,

Let the original price was 100%.

When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.

115\%=\dfrac{115}{100}\\\\=1.15

or

\dfrac{115}{100}=\dfrac{23}{20}

So, this is the required solution.
