Add all three fractions together to get the total growth in 3 weeks.
2 1/2+2 3/4+3 1/4=x (x being how much the sunflower grew in the 3 weeks)
Convert all fractions so they are mixed numbers.
5/2+11/4+13/4=x
11/4+13/4=24/4, or 6
Convert 6 to the fraction 12/2.
5/2+12/2=17/2, or 8 1/2
Hope this helps :)

Answer:
12 days
Step-by-step explanation:
Set up an equation with y = mx + b, where m is the rate and b is the y-intercept (starting value)
Let x represent how many days it takes and y represent how many pages he read:
445 = 24x + 157
Solve for x:
288 = 24x
12 = x
So, it will take him 12 days to finish the book
