Given:
• Ratio of rice to spice = 15 : 1
,
• Mass of spice he has = 40 grams
,
• Number of servings to make = 10
,
• Number of grams of rice in each serving = 75 grams
,
• Amount spent on rice = 4.50 dollars
Let's find the number of servings he can make with the current amount of spice he has.
Where:
Amount of spice he has = 40 grams
Since the number of grams of rice in each serving is 75 grams, we have the ratio:
The new ratio will be:
75 : 5
Now, since he has 40 grams of spice, to find the number of servings, we have:
Therefore, the number of servings he can make with the current spice he has is 8 servings.
ANSWER:
8 servings
