(3.50)(3)÷12+1.35
3 point 5 0 times 3 divided by 1 half plus 1 point 3 5

3[12(3.50)+1.35]

Answer 1

To determine the new cost for 3 orders of popcorn (at half price) and 3 drinks, we need to break it down into the costs of the popcorn and the drinks.

1. The original cost of each order of popcorn is $3.50.
2. Since popcorn is half price after halving the movie's duration, the new cost per order becomes $\frac{3.50}{2}=1.75$.
3. The cost for 3 orders of popcorn is therefore $3\times 1.75=3\times \frac{3.50}{2}=\frac{3\times 3.50}{2}=\frac{10.50}{2}=5.25$.
4. The cost for 3 drinks (at $1.35 each) is $3\times 1.35=4.05$.

Now, combine the costs:

• Total cost for popcorn: $\frac{3\times 3.50}{2}=\frac{10.50}{2}=5.25$
• Total cost for drinks: $3\times 1.35=4.05$

Thus, the expression to find the total cost would be: $$\frac{1}{2}(3\times 3.50)+3\times 1.35$$

This matches the expression: 1 half times open bracket 3 times 3.50 plus 3 times 1.35 close bracket.
