Simple,

6 hours Monday through Friday....

That's 5 days...thus..

6*5=30

Now, the employee also has 3.5 hours Saturday morning, so..

30+3.5=33.5

This employee, though, wants to work 40 hours. The employee has 30.5 so far, to find the rest...

40-33.5=6.5

Thus, the employee needs to work an additional 6.5 hours (h).
3 1/2 hour=3.5 hour
number of work hours=(6 hour/day)(5 days) +3.5 hour=30 hours+3.5 hours=
=33.5 hours.

number of hours that he must work=40 hours - 33.5 hours=6.5 hours

he must work  6.5 hours  (or 6 1/2 hours).

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

The following information is provided in the problem :

Lou topped up the tank with $3.80 per gallon of petrol.

Lou's car's 13-gallon tank held 5.9 gallons.

If he filled the tank, you can determine the total amount of money Lou spent by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.

So the total amount would be:

⇒ (13 - 5.9)(3.80)

⇒ (7.1)(3.80)

⇒ 26.98.

Therefore, the total amount would be $26.98

Peter is reading a 193-page book. He has read three pages more than one fourth of the number of pages he hasnt yet read. How many pages has he not yet read? Estimate how many days it will take Peter to finish the book if he reads about 8 pages per day.

Answers

Let n = the number of pages not read
Then the number of pages read = n/4 + 3
Since the total number of pages is 193, we have

n + n/4 + 3 = 193
5n/4 = 190
n = 152
At 8 pages per day it will take 152 pages/ 8 pages/day = 19 days
