This morning, elena wrote a check in the amount of $42.50. this brought her balance down to –$14.25. suppose n represents elena's balance before she wrote the check.

which equation can be used to represent this situation?

a.
n – 14.25 = 42.50

b.
n + 42.50 = –14.25

c.
n – 42.50 = –14.25

d.
n – 14.25 = –42.50

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
