1.  How much is 18.6% of \$100?  \$18.60

2.  A store paid \$100 for a dress. It raised the selling price by 35%.  But
2.  one week later it lowered that price by 10%.  What was the final
2.  selling price?

\$121.50.  For, 35% of \$100 is \$35, so the selling price went to \$135. 10% of that is \$13.50.  And \$135 − \$13.50 = \$121.50.

3.  The student should know the fractional equivalent of the following.
 1.  a) 50% = 12 b) 25% = 14 c) 75% = 34
 1.  d) 12½% = 18 1.  e)  33 13 % = 13 1.  f)  66 23 % = 23
 1.  g)  10% = 1 10 h)  30% = 3 10 i)  70% = 7 10 j)  90% = 9 10 1.  k)  20% = 15 l)  40% = 25 m)  60% = 35 n)  80% = 45

4.  Write each of the following as a fraction, or a whole number, or a
3.  mixed number.

 1.  a)  79% = 79 100 b)  3% = 3  100 c)  60% = 35
 2.   d)  100% = 1 1.  e)  300% = 3 f) 350% = 3 12
 2.   g)  375% = 3 34 h)  333 13 % = 3 13 i)  480% = 4 45

15.  How much is

 a)  75% of \$208?  \$156 b)  250% of \$16?  \$40 c)  325% of 200?  \$650 d)  75% of \$37.60?  \$28.20 e)  675% of 400?  \$2,700 f)  12.5% of \$96.24?  \$12.03 g)  30% of \$62?  \$18.60 h)  40% of \$96?  \$38.40 i)  40% of \$55?  \$22.00 j)  20% of \$148?  \$29.60 k)  20% of \$150?  \$30.00 l)  70% of \$312?  \$218.40

16.  Thirds.  How much is

 a)  33 13 % of 81?  27 b)  66 23 % of 81?  54 c)  33 13 % of \$32.40?  \$10.80 d)  66 23 % of \$32.40?  \$21.60

17.  Calculator problems.  How much is

 a)  33 13 % of \$706.14?  \$235.38 b)  66 23 % of \$706.14?  \$470.76 c)  33 13 % of \$91.15?  \$30.38 d)  66 23 % of \$91.15?  \$60.77
