Step-by-step explanation:
think of 10 as a base so like 100 ok and you know if 50 of that is 50 percent 40 would just be forty percent
(g + f)(x)
g(x) + f(x)
x - 1 + x^2 + 4
x^2 + x + 3
(g - h)(x)
g(x) - h(x)
3x + 1 - (2x - 2)
3x + 1 - 2x + 2
x + 3
The bill was actually $25 and the waiter kept $2 so 25 + 2 = $27
$27 / 3 people = $9 per person.
They each originally paid 10, but were given 1 back: 10 - 1 = 9, so they each ended up paying $9 each.. there is no extra dollar.
That would be John Stillwell's aptly titled Mathematics and its History. It teaches you the math along with the history, and is excellent.
