Mr. brown is organizing a camping trip for the students in his scout troop. he has the following breakdown of how much it would cost him per day of the camping trip. campground rental: $200 per day training cost: $20 per student per day food cost: $30 per student per day miscellaneous expenses: $50 per student per day camping gear cost: $1,050 (one-time cost) mr. brown's total cost for organizing a 3-day camping trip with b students is represented by the expression below. which statement best describes the coefficient of b? a. it is mr. brown's total cost per day for campground rental and the camping gear. b. it is mr. brown's daily cost per student for campground rental and the camping gear. c. it is mr. brown's total 3-day cost per student, with training, food, and miscellaneous expenses. d. it is mr. brown's daily cost per student, with training, food, and miscellaneous expenses.

Option C

Step-by-step explanation:

You forgot to attach the expression that models the cost of the camping trip during the three days. However, by analyzing the units, the answer can be reached.

The total cost has to be in units of $.

There are two types of costs in the problem:

Those that depend on the number of days ($/day )

Those that depend on the number of students and the number of days ($/(student * day))

If there are 3 days of camping and b students, then you have to multiply the costs that depend on the days by the number of days (3), and the costs that depend on the number of students you have to multiply them by 'b'

So, if the costs that must be multiplied by 'b' are only those that depend on the number of students, the coefficient of b must be:

3 days (Cost of training + Cost of food Miscellaneous expenses :).

Therefore the correct answer is option C:

C. It is the total cost of 3 days per student of Mr. Brown, with training, food and miscellaneous expenses.

The expression that represents the total expense should have a formula similar to this:

y = 3 ($ 100b + $ 200) + $ 1050

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
