Bill and mary ann went to the viola bakery. bill bought 3 danishes and 8 filled donuts for $14.67. mary ann bought 7 of each for $16.73. what is the price of each type of pastry?

Step-by-step explanation:

Givens

Let's call dánishes and donuts.

Bill's purchase can be expressed as

Mary's purchase can be expressed as

Let's isolate from the first equation

Then, we substitute this equivalence in the second equation

Each donut costs $1.50.

Then, we use this value to find the other one.

The cost per unit of dánishes is 89 cents.

this is false ^.^ lol

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 !
