Gavin is working two summer jobs, making $20 per hour lifeguarding and making $6 per hour walking dogs. In a given week, he can work no more than
10 total hours and must earn at least $90. If x represents the number of
hours lifeguarding and y represents the number of hours walking dogs, write
and solve a system of inequalities graphically and determine one possible
solution.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
