To determine how many inches taller Tonya is than Mary, we can set up a simple subtraction equation using their heights.
**Correct equation:**
\[ \text{Height difference} = \text{Tonya's height} - \text{Mary's height} \]
This translates to:
\[ \text{Height difference} = 70 \text{ inches} - 63.5 \text{ inches} \]
**How to solve:**
1. Subtract Mary's height from Tonya's height:
\[ 70 - 63.5 \]
2. Perform the calculation:
\[ 70 - 63.5 = 6.5 \]
**Correct answer:**
Tonya is 6.5 inches taller than Mary.
