The balance of errands average balance checking account at the beginning of last cycle was $400 and the only transaction for the cycle was a check that Aaron route for $200 which cleared exactly halfway through the cycle on what amount did Aaron's checking account pay interest last cycle

$300

Step-by-step explanation:

Here we are given:

Balance at the beginning of last cycle(first half) = $400

Balance halfway through the cycle(second half cycle) = $200

To find the amount Aaron's checking account pay interest last cycle, let's find the average balance.

Use the formula for average:

Average = $300

Therefore, the amount Aaron's checking account pay interest last cycle is $300

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
