Question

norma recorded the types of pasta dishes sold at the café yesterday.
pasta dish sales
\tgarlic cream sauce\ttomato meat sauce
spaghetti\t10\t90
bowties\t60\t40
based on the table, which statement is true?
of all the pasta dishes sold, 30% had bowties and garlic cream sauce.
a total of 100 pasta dishes were sold.
of the spaghetti dishes, 5% had garlic cream sauce.
half the pasta dishes sold had garlic cream sauce.

Explanation:

Step1: Calculate total pasta dishes sold

First, we sum up all the values in the table. For Spaghetti: \(10 + 90 = 100\). For Bowties: \(60 + 40 = 100\). Total dishes: \(100 + 100 = 200\).

Step2: Analyze each statement

• Statement 1: 30% had bowties and garlic cream sauce

Bowties with garlic cream sauce: \(60\). Percentage: \(\frac{60}{200} \times 100 = 30\%\). This seems possible, but let's check others.

• Statement 2: Total 100

From Step1, total is \(200\), so this is false.

• Statement 3: 5% of spaghetti had garlic cream

Spaghetti with garlic cream: \(10\). Total spaghetti: \(10 + 90 = 100\). Percentage: \(\frac{10}{100} \times 100 = 10\%\), not \(5\%\). False.

• Statement 4: Half had garlic cream sauce

Garlic cream sauce total: \(10 + 60 = 70\). \(\frac{70}{200} = 0.35\) (35%), not 50%. False.

Answer:

Of all the pasta dishes sold, 30% had bowties and garlic cream sauce.
