Answer:
It costs $42.43
Step-by-step explanation:
Lets explain how to solve the problem
- The cost of
kilogram of candy is $7.5
- We need to find the cost of
kilogram
We can use the ratio to find the answer
======= Dollar : Kilogram
======= 7.5 : 
======= c :
By using cross multiplication
∴ c ×
= 7.5 × 
∵
= 
∴
= 
∴ c ×
= 7.5 × 
∴ c ×
= 
Divide both sides by 
∴ c =
÷ 
Change the division sign to multiplication sign and reciprocal the
fraction after the division sign
∴ c =
×
∴ c =
= 42.43 dollars
∵ c represents the cost of
kg
∴ It costs $42.43
