Explanation:

Step1: Define variable for ingredient price

Let $x$ = price of one ingredient.

Step2: Set up total cost equation

Total cost = plain phở price + 4×ingredient price
$\$8 = \$6 + 4x$

Step3: Solve for $x$

Subtract $\$6$ from both sides: $8 - 6 = 4x$ → $2 = 4x$
Divide by 4: $x = \frac{2}{4} = 0.5$

Step4: Identify unknown amount

The problem asks to find the price of each ingredient, which is the unknown.

Answer:

1. The price of each ingredient is $\$0.50$
2. D. price of each ingredient
