Answer:
This is the concept of financial mathematics;
Break even point is defined mathematically as:
Cost=Revenue
At this point the organization doesn't make any profits because the cost is equal to the revenue. Therefore , to solve our expression we proceed as follows;
The question requires us to find the number of units of products that must be sold in order to break even, to solve this we proceed as follows;
At break even;
C=R
but;
C=13x+80
R=18x
hence;
18x=13x+80
putting the like terms together we get:
18x-13x=80
5x=80
dividing both sides by 5 we get:
(5x)/5=80/5
x=16
Therefore the number of units that must be sold in order to break even is:
x=16 units

5.95 is your answer because Eli biked 1 1/10 and then he returned to his home that would be 1 + 1/10 + 1 1/10 = 2.2 but then Eli returned to the library which is 3 3/4 from her home so add 2.2 + 3 3/4 = 5.95
15 miles.
The runner adds two miles every day, so if they continue that pattern, they will run 15 miles on Saturday (13+2)
