The equation y = 7x+25 gives the number of minutes it takes to prepare a meal y given the number of people being served x. Which statement is true?

A. For every extra minute it takes to prepare a meal, 7 more people can be fed.

B. For every extra minute it takes to prepare a meal, 25 more people can be fed.

C. For every extra person served, the time it takes to prepare a meal increases by 7

minutes.

D. For every extra person served, the time it takes to prepare a meal increases by 25

minutes.

Given equation y=7x+25.

where x represents number of people being served and y represetns number of minutes it takes to prepare a meal.

Number of people can be taken for x variable are 1,2,3,4 ...

From the given equation if we plug x=0, it gives y=7 (0) + 25 = 0+25=25.

So, fix number of minutes is 25 minutes to prepare a meal.

If we take x=1, that means we are taking 1 extra person and if we plug x=1 in original function, we get y=7 (1) + 25 = 7+25.

So, it is taking 7 extra minute to prepare a meal.

Let us check by adding one more person. For that we need to take 1+1=2 number of person.

On plugging x=2, we get y=7 (2) + 25 = 14+25 = 7+7+25.

So every time if we add extra person, the time increase by 7 minutes to prepare a meal.

Therefore, Option "C) For every extra person served, the time it takes to prepare a meal increases by 7 minutes." is correct option.
