How many different positive integer values of x will make this statement true: there is exactly one positive, two-digit multiple of x .
There should be: 49 - 34 + 1 =16 positive values of x that have only one 2-digit multiple. Example:
34 x 2 =68 - Next multiple of 34 is 3-digit 102.
35 x 2 = 70 - Next multiple of 35 is 3-digit 105
.
49 x 2 =98 - Next multiple of 49 is 3-digit 147
