Answer:

3.08$

Explanation:

Lets solve this problem using an algebraic equation.

In this case, I am using the variable "x" as the second package of coffee.

First: x+0.3

Second: x

Third: x+0.66

Setting up the equation. All packages of coffee add up to $10.20.

x+x+0.3+x+0.66 = 10.20

Combine like terms.

3x + 0.96 = 10.20

Subtract 0.96 on both sides.

3x = 9.24

Divide 3 on both sides.

x=3.08
