Question

2. Hal forgot the number of people at the

basketball game. He does remember that
the number had four digits and a 3 in the
tens place. Write a number that Hal could
be thinking of

Answer 1

Well there is a lot of different numbers he could be thinking of because we are only given 2 useful pieces of information: Four Digits, and, a 3 in the tens place (30).

.

This means that the other spaces could be any number.

.

If X represents a random number it would be XX3X.

.

Eg 1234

Answer 2

2235 is a number that Hal could be thinking of because of the number of digits and the 3 being in the right spot.
