There are 3,089 numbers from 1 to 10,000 that contain the digit 7. This can be found by dividing the total number of possible 4-digit numbers (10,000) by the number of possible 4-digit numbers that don't contain the digit 7 (6 x 9 x 9 x 9 = 5,724), and subtracting that result from the total number of possible 5-digit numbers (9 x 9 x 9 x 9 x 5 = 32,085). Therefore, 32,085 - 5,724 = 3,089.
