The numbers 1,2,...,n are written on the board. Every minute, I erase two numbers a and b and replace them with a+b+ab. Clearly, after n-1 minutes there is only one number left on the board. Does the result depend on the order? For which n can I make the resulting number be odd

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
