5(2x - 4) = 45
10x - 20 = 45
10x = 45 + 20
10x = 65
x = 65/10 reduces to 13/2 or 6 1/2
Answer:
<h2>$2479.5</h2>
Step-by-step explanation:
In this problem we will estimate her monthly earnings
given that she earns $13.05 per hour
and also given that she works for 190 hours in a month
then in a month, her earnings will be
=$13.05*190
=$2479.5
alternatively,
per week she works 47.5hours
in a week she will earn 13.05*47.7= $622.485
4 weeks make a month
then after one month her earning will be
$622.485*4= $2479.5
This is just one of many ways for this to be done
36.78 can also be written as 36 and 78/100 or 3678/100
2.4 can be written as 2 and 4/100 or 204/100
so we have 3678/100 ÷ 204/100
to divide fractions, you just have to flip the second fraction and multiply across
3678/100 * 204/100
750312/10000
Simplified that would be 75 and 312/10000
hope this helped
