Question

The calories I burn walking can be modeled by the function y = 5x + 100,

with x representing the number of minutes spent walking. How many
calories would I burn if I walked for 75
minutes?

Answer 1

X=75

Y=5X+100

Y=5*75+100

Y=375+100

Y=475

Therefore, you burnt 475 calories if you walked for 75 minutes
