The answer is C it won’t let me do all the steps but I hope it helps
1 of 2 type of lettuces
1 of 4 vegetables
1 of 7 dressings
2*4*7 = 56 different salads
F(x) = 3x - 2
f(8) = 3(8) - 2
f(8) = 24 - 2
f(8) = 22
f(-5) = 3(-5) - 2
f(-5) = -15 - 2
f(-5) = -17
f(8) - f(-5) = 22 - (-17)
f(8) - f(-5) = 39
Hope this helped! Good luck! :)
