Mr. Marvi's Class is fund-raising for a field trip that costs $1254. The school is
giving his class $375 towards the trip. The class decides to fundraise by selling cookie bags for $1.50. If the class had 28 students in it, on average, how many cookie bags will each person
have to sell?

Extra: If each cookie bag cost 20 cents to make, how many additional cookie
bags will the class have to sell to cover the cost of the cookies?

1.50x + 375 = 1254

x = 586

So the class has 28 students and ideally they should all sell a certain amount equally.

so, 586/28 = 20.93 = 21

So in average every student would have to sell 21 bags of cookies

extra:

Just do a new equation

1.5x - 0.20x = 879$

1.3x = 879

x = 676.15 = 676

So they have to sell 676 bags of cookies to cover for the cost of the cookies and for the trip.

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 %
