Afamous fast food chain opened two branches in different parts of a city. branch a made a profit of $50,000 in the first year, and the profit increased by 4% every year. branch b made a profit of $35,000 in the first year, and the profit increased by 5.5% every year.

which function can the fast food chain use to determine its total profit, p(x), after x years, and how much money will the chain have made in profit after 4 years?

The function would be,

The approximate total profit after 4 years is $ 97341.65.

Step-by-step explanation:

Given,

For branch A,

First year profit = $ 50,000,

And, the profit increased by 4% every year.

Thus, the profit of branch A after x years,

Also, for branch B,

First year profit = $ 35,000,

And, the profit increased by 5.5% every year.

Thus, the profit of branch B after x years,

Hence, the total profit,

Which is the required function.

After 4 years, x = 3,

Therefore, the total profit after 4 years would be,

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
