The answer:

the full question is if f(x) = 3 [ x - 2 ] , what is f(5.9)?

9
10
11
12

first, [x - 2 ] is called the integer part of x-2,
generally, to compute f(c) where c is a real number, it is sufficient to substitute the value of x by c.
so f(5.9) = 3 [ 5.9 - 2 ] = 3 [ 3.9 ]

as we know that [ 3.9 ]=3

therefore
3 [ 3.9 ]= 3x3 =9

the answer is 9

goldfiish [28.3K]

The original price was 100% and the sale was -25%
100% - 25% = 75%
This means 75% = £33
75% = 3/4
If we divide the sale amount by 3 and them multiply by 4, we will get the original amount.
£33 / 3 = £11
£11 x 4 = £44
