# 1T = 50(5) + 300
     T = 250 + 300
     T = $550

# 2 f(x) = 3x - 5 , find f(-1)
     f(-1) = 3(-1) - 5
     f(-1) = -3 -5
     f(-1) = -8

# 2 g(x) = -5x + 2 , find g(4)
     g(4) = -5(4) + 2
     g(4) = -20 + 2
     g(4) = -18

# 4 I don't know what formula from above they are talking about but it looks like it could be C = 2*pi*r
C = 4^2
C= 2 * pi* r
16 = 6.28 *  r
divide both sides by 6.28
r = 2.55
