Given : The Number of Correct Answers = 30

Given : Total Number of Questions = 40

⇒ The Number of Wrong Answers = (40 - 30) = 10

The Ratio of the Number of Correct Answers to Number of Wrong Answers is :

\mathsf{\implies \frac{30}{10}}

\mathsf{\implies 3 : 1}  (1st Blank)

The Ratio of the Number of Correct Answers to Total Number of Questions is :

\mathsf{\implies \frac{30}{40}}

\mathsf{\implies 3 : 4}

If there is 100 Questions on the test and the Ratio stayed the same, The Number of Questions he would have answered correctly is :

\mathsf{\implies \frac{3}{4} \times Total\;Number\;of\;Questions}

\mathsf{\implies \frac{3}{4} \times 100}

\mathsf{\implies (3 \times 25)}

\mathsf{\implies 75}  (2nd Blank)

A local yoga studio
Andrews [41]

Answer:

Let's call the first studio, yoga studio A.

Let's call the second studio, yoga studio B.

The equations:

Yoga Studio A: y=10x+55

Yoga Studio B: y=12.5x+25

So, for 12 classes:

Yoga Studio A: y=10(12)+55, y=175

Yoga Studio B: y=12.5(12)+25, y=175

These two numbers are equal, so Griffin is right.

For 10 classes:

Yoga Studio A: y=10(10)+55, y=155

Yoga Studio B: y=12.5(10)+25, y=150.

These two numbers are not equal, so Gigi is wrong.

Let me know if this helps!
