Answer:

18

Step-by-step explanation:

To solve we fist need to figure out what 40% is in decimal form. To do this we have to move the decimal point to the left 2 spaces.

40% -> 0.40

Then we can multiply...

45 · 0.40 = 18  (This means that 40% of the total 45 students is 18).

Question: 3 of 20
zysi [14]

Answer:

Sean earns $7.5 in each hour.

Step-by-step explanation:

Given:

Money earned by Sean = $300

Number of hours worked in a day = 8 hrs

Number of days of work  in a week = 5

We need to find Money earned in each hour.

First we will find Total hours work in a week.

Total hours work in a week is equal to Number of hours worked in a day multiplied by number of days work in a week.

Framing in equation form we get;

Total hours worked in a week = 8\times5 = 40\ hrs

Now we will find money earned for each hour.

Money earned each hour will be calculated by Dividing Total Money earned in a week by Total number of hours worked in a week.

Framing in equation form we get;

Money earned each hour = \frac{300}{40} = \$7.5

Hence Sean earns $7.5 in each hour.
