21 minutes is the answer because there's 45 minutes between 11: 15 and 12:00 and the 3 activities for eight minutes (8 x 3 = 24) so 45 - 24 = 21 minutes
C = 4900 + 175S
The graph will cross the y-axis at 4900 and show a slope of 175/1 . Good luck graphing. If you choose the right scale, the graph will be easier. Increment by by 500 on the yaxis and 25 on the x-axis.
2x-3 is the correct answer
Y-70
X-30
Z-80
