To create the equation for the total cost \( y \) in terms of the number of kites purchased \( x \), we need to consider both the cost of the kites and the shipping cost.
- The cost of each kite is $6, so the total cost for \( x \) kites is \( 6x \).
- There is a flat rate shipping cost of $10.
Thus, the total cost \( y \) can be expressed as:
\[ y = 6x + 10 \]
This equation represents the total cost \( y \) in terms of the number of kites purchased \( x \).
