Answer:
2/4, 3/6, 4/8, 5/10, 6/12, etc
<span><span>If Mike saves 20% of every paycheck and his paycheck last week was $1500, you can calculate how much money Mike saved from that paycheck using the following steps:
20% * 1500 = 20/100 * 1500 = 20 * 15 = $300

Answer:
b. 85
Step-by-step explanation:
Average grade (μ) = 75
Standard deviation (σ) = 8
Assuming a normal distribution, the z-score corresponding to the upper 10% of the test grades is z = 1.28.
The minimum grade 'X' within the top 10% is given by:
Rounding to the nearest percent, the dividing point between an A and a B grade is 85.
Answer: The man was worse off than in 2005
Step-by-step explanation:
Assume the man's salary in 2005 was $4,500.
In 2006 therefore, his salary goes to:
= 4,500 * (1 + 10%)
= $4,950
In 2007, this drops by 10%:
= 4,950 * ( 1 - 10%)
= $4,455
<em>The man was worse off than in 2005 because the 10% reduction was based on the larger 2006 salary but the 10% increase was based on the smaller 2005 salary. </em>
