No it is not an irrational number
Well, we know that the two consecutive numbers have to be negative, because if it was positive, the smaller number multiplied by two would be much greater. (unless 1 and 2). So, by guessing and checking, we will get -13 and -14 :)
Answer:
The minimum amount of sales needed to cover its expenses is $15,000
Step-by-step explanation:
Let
s ----> the amount of sales
we know that
The amount of sales s multiplied by the percentage of commission (42%) plus the fixed rate of $2,500 must be greater than or equal to $8,800 a month
so
The inequality that represent this situation is
solve for s
subtract 2,500 both sides
divide by 0.42 both sides
therefore
The minimum amount of sales needed to cover its expenses is $15,000
