Ataxi cab charges $0.55 per mile in addition to a $1.75 flat rate fee. susie has $10 to spend on a taxi cab ride. the taxi driver will not give anyone a ride unless they are going somewhere that is more than 2 miles away. model susie’s situation with a system of inequalities.

The taxi driver doesn't give anyone a ride unless it's 2 miles away, as such you need to add at least $0.55x2 in addition to the $1.75 at the start
1.75+(0.55x2)=2.85
As Susie only has 10 dollars to spend, she can't exceed that. So Susie must spend more than $2.85(minimum from the taxi) and less than $10(her money)
so,
$2.85<Susie<$10

The answer is that the rate of change is $50 per 1 monthhope this ; )
