Final answer:
To find the price of each ingredient, subtract the price of the plain pho from the total with 4 ingredients. Divide the difference by 4 to get the price of each ingredient: 0.5
Step-by-step explanation:
To find the price of each ingredient, we need to subtract the price of the plain pho from the total price with 4 ingredients added. The difference will give us the total cost of the ingredients. We can then divide the total cost of the ingredients by 4 to find the price of each ingredient.
Let's say the price of each ingredient is x. So we have the equation: 6 + 4x = 8.
Solving for x:
4x = 8 - 6
4x = 2
x = 2/4
x = 0.5
Therefore, the price of each ingredient is 0.5.
