1. Cost = room rental + transportation
Let units of cost be "dollars" and let "n" represent the number of people going on the field trip.
.. cost = 637 +18n
.. revenue = 105 +25n

2. You want to find "n" so that revenue matches cost.
.. revenue = cost
.. 105 +25n = 637 +18n
.. 7n = 532
.. n = 76
76 people need to make the trip to break even

What is the least common multiple of the numbers 5, 25, and 15? OA. 25 OB. 50 O C. 75 OD. 100 O E. 125

Blizzard [7]

The answer is C. 75.

Explanation: Let’s go from smallest to largest.

A, 25, would not work because you can’t multiply 15 by a whole number to get 25.

B, 50, doesn’t work because again, you can’t multiply 15 with a whole number to get 50.

C, 75, is the CORRECT ANSWER because 5x15 is 75, 25x3 is 75, and 15x5 is 75. Each number can be multiplied by a whole number to get 75.
