Pretest Answers and Explanations
1 b First, find the total mileage; 135 + 162 + 98 +
117 + 216 = 728 miles Divide the total mileage
(728) by the number of miles covered for each
gallon of gas used (14) to find the number of
gallons of gas needed; 728 ÷ 14 = 52 gallons
2 b 1 ft = 12 in 9 ft 8 in = 9 × 12 + 8 = 116 in.;
116 ÷ 4 = 29 in = 2 ft 5 in
3 b To find the perimeter of the figure, find the sum
of the lengths of the four sides: 2a + b + a + 3b + 3a + b + 3a + 2b = 9b + 7b.
4 c Michael has $30 Siobhan has $30 − $3 = $27 Jossie has $27 + $5 = $32
5 b To find 5% of a number, multiply the number
by 05: 180,000 × 05 = 9,000 There are 9,000 food service workers in the city
6 d M = number of persons in trade and finance.
Since M = 25% of the total, 4M = total number
of city workers Number of persons in manufac-turing = total number of workers3 = 43M
Personal Service 12%
Professional 8%
Food Service 5%

Trade and Finance 25%

Trang 47 c Since pairs of alternate interior angles of parallel
lines have equal measures, m∠BCD = m∠ABC
Thus, m∠BCD = 112°
m∠ECD = 12m∠BCD = 12(112) = 56°
8 e In two weeks, Mr Delandro worked a total of
(42 + 37) hours and earned $12 for each hour
Therefore, the total number of dollars he earned
was 12(42 + 37)

Pretest Assessment
How did you do on the math pretest? If you answered seven or more questions correctly, you have earned the equivalent of a passing score on the GED Mathematics Test But remember that this pretest covers only a frac-tion of the material you might face on the GED exam It
is not designed to give you an accurate measure of how
you would do on the actual test Rather, it is designed to help you determine where to focus your study efforts For success on the GED, review all of the chapters in this section thoroughly Focus on the sections that corre-spond to the pretest questions you answered incorrectly
