Answer:
10(3^(5-n))
Step-by-step explanation:
A product is negative when the number of negative numbers in the multiples is odd.
Therefore, options A and C gives negative products.
First, convert 1 kg to g.
1 kg = 1000 g
So 1000 g = 1.28
Set up a proportion:
1000/1.28 = 250/x
Cross multiply:
1000x = 320
Divide 1000 to both sides:
x = 0.32
So 250g costs £0.32
Step-by-step explanation:
option C is the correct answer: -100°
