After purchasing a cell phone online, mary attempts to sell the phone for $325. if this was a markup of 24%, how much did mary originally buy the phone for?

Mary bought the phone for 1350

Step-by-step explanation:

The price mary bought the phone shall 100%

$325 is 24% of the price which she bought it.

So if $325 is equal to 24% , what shall 100 percent represent?

In order to find the answer to this, we cross multiply as follows;

24% = $325

100% = ?

cross multiply the above to get,

( 325 * 100 ) / 24

The abouve gives us the answer 1350

So 1350 is the original buying price of the phone.

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%

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 !
