Answer:
Trisha has two boxes of marbles than
to find probability
use formula
probability =no.of given marble/total no of marble
They each would pay 2.55
12.75 divided by 5 = 2.55
We need to calculate which is higher...2.5% OR $40.
1950 * .025 = $48.75
Thus, 2.5% is higher than $40. So, if allowed, she would opt for the $40 payment.
