Sally earns per hour = $12
Sally works for in a week = 16 hours.
So, Sally earns in a week = 
Sally can save money each week= 20% of 192

A. How much does she earn each week ? Sally earns $192 in a week.
B. How much money will she save each week? Sally will save $38.40 each week.
C. How much money will she save each month (assume there are 4.3 weeks in a month)
Savings of 1 week = $ 38.40
Savings of 4.3 weeks = 
Hence, she will save $165.12 in a month.
D. How many months will it take her to save the money?
Total money needed = $1800
Number of months needed to collect this amount =

Hence, it will take 11 months approx to save $1800.
2.5 b = 27.5
b = 27.5 / 2.5
b = 11

Answer:</h2>
<u>The expression is</u><u> 5(40+80)</u>
<h2>
Step-by-step explanation:</h2>
The sum of 40 and 80 can be written as
(40+80)
and when we take the 5 times of the sum
we can write as
5(40+80)
well, it's isosceles so use base angles theorem
the top angle is also x
90 + 2x = 180
subtract 90 from both sides
2x = 90
divide both sides by 2
x = 45 degrees
I think it is a Convience Sampling.
