Answer:

92.5%

Step-by-step explanation:

shaded squares/total squares = 185/200

simplify:

(185/5)/(200/5) = 37/40

37/40= 35/40 + 2/40

32/40 + 5/40 = 4/5 + 1/8

4/5 + 1/8 = 0.8 + 0.125

0.8 + 0.125 = 80% + 12.5%

80% + 12.5% = 92.5%

How do I solve this?? I'm lost
Alekssandra [29.7K]
Your insight that the function values differ by 5 every time is very important. So your f(x) will contain 5x as a term. You have to find a constant to add or subtract to make sure f(1)=-2.

f(x) = 5x-7 does the job.
