Martin is making a candy that contains 90% milk chocolate and the rest caramels. The candy has 3 pounds of caramels.

Part A: Write an equation using one variable that can be used to find the total number of pounds of milk chocolate and caramels in the candy. Define the variable used in the equation.

Part B: How many pounds of milk chocolate are present in the candy? Show your work.

This the concept of algebra, let the amount of milk m and that of caramel be c. Total amount of chocolate will be p.

The amount of caramel=3 pounds;

The amount of milk=90%=0.9/0.1*3=27 pounds milk

Therefore the total amount of milk in candy will be:

m=0.9p

The total amount of caramel will be:

c=0.9p

Percentage of Caramel in chocolate is 10%. The amount of milk will therefore be:

0.9/0.1*3=27 pounds
