The height is 3. I have a pic to show the work
S = 60W + 650 <== ur equation
after 18 weeks...so sub in 18 for W
S = 60(18) + 650
S = 1080 + 650
S = 1730 <==
The answer #6 is j. 100. He uses the treadmill for 40% so that means 60% of his exercise is not on the treadmill.
40%= 40 mins
60%= 60 mins
total: 100%= 100 mins.
Hope this helps!
