A)$278.99
B)$268.46
C)$354.22
D)$317.54

Accepted Answer

The mean for the data set above is $268.46. The median or middle number when the numbers are in ascending order ($79.84, $98.12, $111.39, $278.99, $342.16, $466.25, $502.47) is $278.99.

Question 2

The wholesale price of a fountain pen is $2.80. What will the new price be if a 5% increase is instituted?
A)$2.84
B)$2.90
C)$2.94
D)$2.96
E)$2.97

Accepted Answer

To find 5% of a number, first find 10%, then halve it. In this case, 10% of $2.80 is $0.28. Half of that is $0.14. Add the 14 cents to $2.80 to get $2.94.
Key Takeaway: Logical reasoning is critical with percent problems. Knowing how to manipulate numbers in relation to "friendly" numbers is important. For example, to find 5%, halve 10%. To find 20%, double 10%.
