Answer 2) 10 weeks is the correct answer
Measurement includes using percentages. Here you need to have an understanding of how percentages work. Additionally, you need to recall how to convert a percent value into a decimal. Some examples of this are:
-
100% = 1
-
50% = .5
-
25% = .25
-
5% = .05
Joe’s net pay, after taxes, is $325 per week (P). Saving at a rate of 20% (R) each week, Joe put away the following sum (S):
-
The decimal equivalent of 20% is .20 = R
-
P x R = S
-
$325 x .20 = $65 per week
To save a total of $600, Joe would have to save this amount for 10 weeks. A simple calculation for this is:
-
600/65 = 9.2 weeks
Since employers do not pay partial weeks, Joe would have to save for 10 weeks.
