He paid ...
-- The cost of the lunches (100% = 1.00 of it)
-- 15% of the cost as a tip (15% = 0.15 of it)
-- 12% of the cost as sales tax (12% = 0.12 of it)
Total that he paid = (1.00 + 0.15 + 0.12) = 1.27 of $248.40

Answer:
x = -2,1, 2
Step-by-step explanation:
g(x) = (x + 2)(x − 1)(x − 2)
Assuming we are looking for the roots
0 = (x + 2)(x − 1)(x − 2)
Using the zero product property
0 = x+2 0 =x-1 0 = x-2
x=-2 x = 1 x =2
