Jayden and Carson are selling T-Shirts and sweatshirts with the school logo. Jayden sells 9 T-Shirts and 3 sweatshirts for 288$. Carson sells 1 T-Shirt and 6 sweatshirts for 270$. Find the selling prices of each item

cost of T-shirts = $18

cost of sweatshirt = $42

Step-by-step explanation:

Let the cost of T-shirts be x

Let the cost of sweatshirt be y

The information given in the question can be used to form an equation that'll be:

9x + 3y = 288 i

1x + 6y = 270 ii

Multiply equation i by 1

Multiply equation ii by 9

9x + 3y = 288 iii

9x + 54y = 2430 iv

Subtract iii from iv

51y = 2142

y = 2142 / 51

y = 42

The cost of a sweatshirt is $42

Since Carson sells 1 T-Shirt and 6 sweatshirts for 270$. The cost of a t-shirt will be:

= 270 - 6(42)

= 270 - 252

= $18

answer: 590

step-by-step explanation:

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 !
