It's not a "hard" problem at all. Can be solved by setting some equations.
Let x be the price of the ice cream and y be the price of the chip.
We got a system of equations:

x + y = 1.1 (1)
x - y = 1 (2)

Solve it by adding (x - y) to (x + y) and 0.1 to 1.1. We get 2x = 2.1 => x = 1.05.
We get y = 0.05 by using the (1) equation.

\( \frac{($1.10-$1)}{2} \) this is a formula.when a question tells you total value of 2 items \( A \) and difference between their price \( B \),the value of the more expensive item is \( \frac {A+B}{2} \) and the value of the cheaper item is \( \frac {A-B}{2} \)

is it 0.5$....a question of this type was asked in challenges....few weeks ago...:)

It is actually 0.05$.
