On his first day working out, Anthony did
30 push-ups. On each successive day, he
did exactly 3 more push-ups than on the
previous day. After completing his push-ups
on the 30th day, how many push-ups had
he completed on all 30 days?	Choose the correct choice from the following
A) fewer than 500 B) between 500 and 1,000 C) between 1,000 and 1,500 D) between 1,500 and 2,000 E) more than 2,000
Anthony completed 30 push-ups the first day, 33 the second day, 36 the third day, and   so on. Make a chart as follows:   1 2 3 4 5 . . . 10 . . . 15 . . . 20 . . . 25 . . . 30   30 33 36 39 42 57 72 87 102 117   To save time adding all these numbers, notice that the total of the first and 30th numbers   is  30 + 117=

<output>147</output>
147. This total is the same for the 2nd and 29th, the 3rd and 28th, and so on all   the way to the 15th and 16th. Therefore, you have 15 pairings of days on which Anthony   completed 147 pushups. You can simply multiply to find the total: 147 × 15= 2,205.   correct answer more than 2,000) more than 2.000
