Question

Jalen is in a 24 hour dance-a thin as part of a fundraiser. He raised $50 in the first hour of competition. Then another 60 in the second hour. Then another $72 dollars in the third hour. If this pattern continues what is the total amount of money he will earn if he stays in the entire competition

Answer 1

Answer: $786

Explanation:

first hour = $50

Second hour = $60

Third hour = $72

Total amount after 24 hours :

4th hour = 72 + 1 4 = 86

5th = 86 + 16 = 102

6th = 102 + 18 = 120

7 = 120 + 20 = 140

8 = 140 + 22 = 162

9 = 162 + 24 = 186

10 = 186 + 26 = 212

11 = 212 + 28 = 240

12 = 240 + 30 = 270

13 = 270 + 32 = 302

14 = 302 + 34 = 336

15 = 336 + 36 = 372

16 = 372 + 38 = 410

17 = 410 + 40 = 450

18 = 450 + 42 = 492

19 = 492 + 44 = 536

20 = 536 + 46 = 582

21 = 582 + 48 = 630

22 = 630 + 50 = 680

23 = 680 + 52 = 732

24 = 732 + 54 = 786
