1) The first expression is found by using the formula retail price = original cost + markup. If p is the original price, then the expression is p + 0.1p. The second expression can be found by simplifying the first expression. This gives 1.1p

b) Substituting p = 28 into the second expression gives 1.1(28) = 30.8 so the selling price is $30.80
