Jeff and Sarah are going to the movies. Sarah wants large popcorn for $9.50, and Jeff wants Skittles for $5.99. They both get a medium soda for $3.00 each. Their two tickets cost $20.00, but they had a discount of $6.00. Write and solve a Numerical expression to find the total cost.

(9.50 + 5.99) + (3.00 x 2) + (20.00 - 6.00) = $35.49
