Mary sells homemade jewelry through an online shop. She found that each time she increases the price of each necklace by $2, she sells three fewer necklaces per week. Mary generally charges $12 for each necklace, and she typically sells 30 necklaces per week. The
factored form of the equation below represents the revenue, R(x), after x price increases of $2.
R(x) = (12 + 2x)(30 – 31)

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 %
