total cost, $p$ bags of popcorn and $d$ drinks:

Explanation:

Step1: Calculate popcorn cost (5 bags)

$\text{Cost of 5 popcorn bags} = 5 \times 5.50 = 27.50$

Step2: Calculate drink cost (7 drinks)

$\text{Cost of 7 drinks} = 7 \times 3.50 = 24.50$

Step3: Sum for total fixed cost

$\text{Total fixed cost} = 27.50 + 24.50 = 52.00$

Step4: Generalize for p and d

$\text{Total variable cost} = 5.50p + 3.50d$

Answer:

Total cost, 5 bags of popcorn and 7 drinks: $\$52.00$
Total cost, $p$ bags of popcorn and $d$ drinks: $\$5.50p + \$3.50d$
