Question

The attendance on the first day of a carnival was 425 people. The attendance on the third day was 575 people. Assuming attendance will increase linearly each day, how many people will attend the carnival on the sixth day?

a)650
b)725
C)800
d)875

Answer 1

suppose x=day
y=total attendances
on the first day (x=1) ,y=425
on the third day (x=2), y=575

the equation of a line is
y=mx+b
plug the value of x and y
425 = m + b
575 = 3m + b
solve that , you'll get m=75
and b= 350

so the equation of the line is
y = 75x + 350

if you want to find the number of attendances on sixth day, plug x=6 , you'll get the value of y(attendances)
y = 75(6) + 350 = 800
