False True 33 10% of 30 is 3. 30 + 3 = 33L. An increase of 20% can be represented with a multplier of 1.20. Therefore, if ࠵? is the original number of members, 1.20࠵? = 60 and ࠵? = 50. The original number of gym members. \$20 to \$24 indicates an increase of \$4. 4/20 = 20/100 = 20%. \$15 to \$18 indicates an increase of \$3. 3/15 = 20/100 = 20%. The percentage increases are equal!

SOLUTIONS DISCUSSING THE CULMINATION QUESTION Consider an wage increase that happens by adding \$6 to the original amount: \$12 an hour increases to \$18 an hour, \$44 an hour increases to \$50 an hour, \$99 an hour increases to \$105 an hour. 1) In which of the cases above is the percentage increase the largest? 2) At what starting value is an increase of \$6 equivalent to a 6% increase? 3) At what starting value is an increase of \$ ࠵? equivalent to an ࠵? % increase? + , will always be a larger value when ࠵? is smaller, so \$12 to \$18 an hour is the largest increase. We want the \$6 to be 6% of the starting value; this happens with \$100. In general, ࠵? % is , ".. . If we want ࠵? , ".. = ࠵?, then the /100 part needs to cancel with the ࠵? . This can only happen with ࠵? = 100, so this will always happen only with \$100 exactly.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
