Question

Mary is 65.3 inches tall and her sister Tonya is 68 inches tall. Tonya wants to know how many inches taller she is than Mary. Which equation and solution can be used to solve this problem?(3 points)

Answer 1

To determine how many inches taller Tonya is than Mary, you can use the following equation:

\[
\text{Height difference} = \text{Tonya's height} - \text{Mary's height}
\]

Substituting the heights of Tonya and Mary into the equation:

\[
\text{Height difference} = 68 \text{ inches} - 65.3 \text{ inches}
\]

Now, we can calculate the height difference:

\[
\text{Height difference} = 68 - 65.3 = 2.7
\]

So, the equation is:

\[
\text{Height difference} = 68 - 65.3
\]

And the solution is:

Tonya is **2.7 inches** taller than Mary.
