To determine the new cost for 3 orders of popcorn (which are now half price) and 3 drinks, we can set up the expression as follows:
- The original price of one order of popcorn is $3.50, so at half price it becomes $3.50 / 2 = $1.75.
- The price of one drink is $1.35.
- The total cost for 3 orders of popcorn at half price is 3 * $1.75.
- The total cost for 3 drinks is 3 * $1.35.
Putting this all together, the expression for the total cost becomes:
Total cost = 3 * (1/2 * 3.50) + 3 * 1.35
This matches the second choice: 1 half times open bracket 3 times 3 point 5 0 plus 3 times 1 point 3 5 close bracket.
So, the correct response is: 1 half times open bracket 3 times 3.50 plus 3 times 1.35 close bracket.
