The shaded region in the figure shows recommended weight and height combinations. determine the recommended weight range for a person who is 78 inches tall.

5h - w = 170
for h = 77
w = 5h - 170
w = 5*77 - 170
w = 385 - 170
w = 215

Your answer is : w = 215 

Have an amazing day and stay hopeful!

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
