Jason's part-time job pays him $155 a week. if he has already saved $375' what is the minimum number of weeks he needs to work in order to have enough money to buy a dirt bike for $900

He needs to work for a minimum of 4 weeks

Step-by-step explanation:

Amount he has saved=$375

Amount he needs to earns to buy a dirt bike=He earns $155 per week=155×Number of weeks he's worked(N)

This can be expressed as;

The total amount he earns=(Amount saved)+(Amount he earns per week)

Where;

Amount he needs to earn to buy a dirt bike=$900

Amount saved=$375

Amount he earns per week=155N

Replacing in the expression above

900=375+155N

900-375=155N

525/155=155N/155

N=3.4 weeks

Number of weeks=N=3.4 weeks

Minimum Number of weeks he needs to work=4 weeks

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

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 !
