Explanation:
6 is the initial cost, .08 is the cost per minute and 19.68 is the total, set up an equation that looks like this: (x is the unknown variable)

The number of servings of pasta were in the dish Lois made is 31.67.
<h3>Unit value</h3>
- Number of cups of pasta Lois made = 6 1/3 cups
- A serving of the pasta = 0.2 cups
Number of servings of pasta were in the dish Lois made = Number of cups of pasta Lois made / A serving of the pasta
= 6 1/3 ÷ 0.2
= 19/3 ÷ 0.2
= 19/3 × 1/0.2
= (19×1) / (3 × 0.2)
= 19/0.6
= 31.6666666666666
Approximately,
