Yesterday you borrowed $30 from your brother. Every day that you don't pay it back, you owe $2.00 more. So today, day 1, you owe him $32.00; on day 2 you will owe him $34.00; on day 3 you will owe him $36.00, etc. If you still haven't paid him back, how much will you owe him on day 22? Possible answers:
$44.00
$660.00
$74.00
$662.00
Answered by Sandra
I calculate $660.00
Answered by Reiny
day1 = 30+2
day2 = 30+2(2)
day3 = 30+3(2)
...
day10 = 30+10(2)
...
day22 = 30+22(2) = 74

Doesn't 660 seem totally illogical?
