A rental car company charges a base fee of $15.00 plus $0.35 per mile driven. which of the following equations models the charge, c, for renting a car based on the number of miles, m, driven? 1) c=15.00m + 0.35
2)c=0.35(m+15.00)
3)c=0.35m+15.00
4)c=15.00(m+0.35)

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
