jamie and stella are saving money to sign up for a school trip to washington, d. c. in order to sign up for the trip, they must pay $600 upfront. jamie earns his money by washing cars for $25 each. stella earns her money by making pecan pies for $15 each. jamie earns more money than stella does because stella only has enough supplies to make 40 pies. x represent the number of cars jamie washes. let y represent the number of pies stella makes.

part 1: write a constraint (an inequality) to represent how much money jamie needs for his trip.

part 2: write a constraint (an inequality) to represent how much money stella needs for her trip.

part 3: write a constraint (an inequality) to represent the relationship between jamie's earnings and stella's earnings.

part 4: can stella afford to sign up for the trip with the money she earns? explain your answer and show any work that might support your answer.

Please see the answer below:

Step-by-step explanation:

Part 1.

25x ≤ 600  

Part 2.

15y ≤ 600  

Part 3.

25x ≤ 15y  

Part 4.

Stella sells pecan pies for $15 each and has enough supplies  to make 40 pies;

which means, Stella earns each day;

15 x 40

= $600

Hence Stella has enough money to sign up for the trip.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
