(7 × 10) × (2 × 2) = 280
(7 × 100) × (2 × 3) = 4200
Use inductive reasoning to predict the next number in the sequence.
2) 2, 8, 14, 20, 26
Estimate the answer by rounding.
3) 98 + 37 + 66 + 62 + 18
4)

Construct a Venn diagram illustrating the following sets.
7) U = {2, 4, 6, 8, 10, 12}
A = {2, 6, 10}
B = {2, 4, 8}
C = {2, 8, 10, 12}
Solve the problem.
8) Monticello residents were surveyed concerning their preferences for candidates Moore and Allen in an upcoming

Solve the problem. Where appropriate, round to the nearest tenth of a percent.
13) The price of a printer was reduced from $400 to $ 300. What was the percent decrease?
Find the simple interest. (The rate is an annual rate unless otherwise noted. Assume 360 days in a year.)
14) p = $800, r = 7%, t = 1 years
Use the compound interest formula to compute the total amount accumulated.
15) $11,000 for 4 years at 3% compounded annually
Find the mean of the set of data. Round your answer to the nearest tenth.
16) 6, 16, 13, 18, 12, 13, 1, 2, 10
Find the median of the set of data.
17) 4, 7, 19, 24, 30, 39, 49
Find the mode or modes for the set of numbers.
