Explanation:

Question #3

• Option A: Mr. Bovine's class has 10 girls and 18 boys. The ratio of girls to boys is \(10:18 = 5:9\), not \(9:5\). So A is false.
• Option B: Ms. Cody's class has 14 boys and \(14 + 12 = 26\) total students. The ratio of boys to total students is \(14:26 = 7:13\). So B is true.
• Option C: Ms. Davidson's class has 10 boys and 15 girls. The ratio of boys to girls is \(10:15 = 2:3\), not \(2:5\). So C is false.
• Option D: Mr. Enoch's class has 16 girls and \(12 + 16 = 28\) total students. The ratio of girls to total students is \(16:28 = 4:7\), not \(3:7\). So D is false.

Step1: Calculate price per pizza for Alfredo’s

Alfredo’s has 3 pizzas for $26.97. Price per pizza = \(\frac{26.97}{3} = 8.99\) dollars.

Step2: Calculate price per pizza for Giovanni’s

Giovanni’s has 4 pizzas for $37.00. Price per pizza = \(\frac{37.00}{4} = 9.25\) dollars.

Step3: Calculate price per pizza for Luigi’s

Luigi’s has 5 pizzas for $45.75. Price per pizza = \(\frac{45.75}{5} = 9.15\) dollars.

Step4: Calculate price per pizza for Mario’s

Mario’s has 6 pizzas for $52.50. Price per pizza = \(\frac{52.50}{6} = 8.75\) dollars.

Step5: Compare the prices

\(8.75 < 8.99 < 9.15 < 9.25\). So Mario’s has the lowest price per pizza. Wait, but let's check again. Wait, maybe a typo? Wait, the options: A is Alfredo’s, B is Giovanni’s, C is Luigi’s, D is Mario’s? Wait, no, the calculation: Mario’s: 52.50 /6 = 8.75, Alfredo’s: 26.97/3=8.99, Luigi’s: 45.75/5=9.15, Giovanni’s: 37/4=9.25. Wait, but the options: Wait, the user's image: Mario’s is option D? Wait, no, the calculation shows Mario’s has the lowest price. Wait, but let's re - check. Wait, maybe the table: Alfredo’s: 3 pizzas, $26.97. 26.97/3 = 8.99. Giovanni’s: 4 pizzas, $37.00. 37/4 = 9.25. Luigi’s: 5 pizzas, $45.75. 45.75/5 = 9.15. Mario’s: 6 pizzas, $52.50. 52.50/6 = 8.75. So Mario’s (option D) has the lowest price per pizza. Wait, but maybe I misread the options. Wait, the options are A: Alfredo’s, B: Giovanni’s, C: Luigi’s, D: Mario’s. So the best price (lowest) is Mario’s. But wait, maybe the user's table has a typo? Wait, no, according to the calculation, Mario’s has the lowest price per pizza. Wait, but let's check again. Wait, 52.50 divided by 6: 68 = 48, 52.50 - 48 = 4.50, 4.50/6 = 0.75, so 8.75. Alfredo’s: 26.97/3: 38 = 24, 26.97 - 24 = 2.97, 2.97/3 = 0.99, so 8.99. So Mario’s is cheaper than Alfredo’s. So the answer is D. But wait, maybe the original problem has different numbers? Wait, no, based on the given numbers, Mario’s has the lowest price per pizza.

Answer:

B. The ratio of boys to total students in Ms. Cody’s class is 7 : 13
