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 : ![\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D)
======= c :
By using cross multiplication
∴ c ×
= 7.5 × ![4\frac{5}{7}](https://tex.z-dn.net/?f=4%5Cfrac%7B5%7D%7B7%7D)
∵
= ![\frac{4*7+5}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B4%2A7%2B5%7D%7B7%7D)
∴
= ![\frac{33}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B33%7D%7B7%7D)
∴ c ×
= 7.5 × ![\frac{33}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B33%7D%7B7%7D)
∴ c ×
= ![\frac{495}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B495%7D%7B14%7D)
Divide both sides by ![\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D)
∴ c =
÷ ![\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D)
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
2 7/8= 2/3L
Divide both sides by 2/3 and get 4.31 or 4 5/16
