A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. He started at 90 kilograms and gained weight at a constant rate of 8 lbs. a week.

a. Write a function to represent this situation. Use x and y as your variables.

b. What would his weight be after 8 weeks?

Answer 1

a) y= 8x+90 b) 154 pounds

Explanation:

a) 90 will be the initial value (b) and 8 will be the slope (m)

b) to find his weight after 8 weeks plug in x=8

y= 64+90

y=154
