Explanation / Answer

As given we have,

y = 4x + 20

where,

y is the number of people attending a picnic

x is the number of flyers used to advertise it

we can see that,

If x = 0 then y = 0 + 20 = 20

If x = 1 then y = 4 + 20 = 24

If x = 2 then y = 8 + 20 = 28

Hence we can see that when x is increased by 1 then y is increased by 4

Hence we can say that for every extra flyer used in advertising the attendance increases by 4 people

Hence we can say that option 4) is the correct answer
