Since you did not specify how large these integers could be,
there would be an infinite number of them.
However, if you restrict it to 2 digit integers, then the only possible
tens digit would be 7, 8, 9 and the only possible unit digits are 0, 1, 2, 3, and 4
so there would be 3*5 or 15 of them .
they would be easy to list:
70, 71, 72, 73, 74, 80, .... , 93, 94
how many intergers are there for numbers with tens greater or equal to 7 and for units less or equal to 4
