85p per (1/2) kg.
1 kg = 1000g, (1/2)kg = (1/2) * 1000 = 500 g
It means:
500g cost 85p
1g would cost 85p/500
100g would then cost (85p/500) * 100 = 19p
Cost of 100g is = 19p
Hope this explains it.
We are given the functions:
P (x) = 0.9 x
C (x) = x – 150
We can generate two composition functions from the given
two functions in the form of:
<span>P [C (x)] and
C [P (x)]</span>
Since the problem states that we are to find for the final
price after a 10% discount is followed by a $150 coupon then we should
find for:
C [P (x)]
The value of C [P (x)] can obtained by plugging in the
value of P (x) into x in the equation of C (x), therefore:
C [P (x)] = [0.9 x] – 150
<span>C [P (x)] = 0.9 x – 150 (ANSWER)</span>
Answer:
36
Step-by-step explanation:
Let's start by taking two of the smallest prime numbers: 2&3
Then we square both of them:
2²=4
3²=9
Then we multiply 4*9 to get 36.
