To write the equation for the total cost \( y \) in terms of the number of kites purchased \( x \), we need to account for both the cost of the kites and the shipping cost.
For Kites-R-Fun (your company):
- The cost per kite is $6, so the total cost for \( x \) kites is \( 6x \).
- There is a flat shipping rate of $10.
Putting this together, the equation for the total cost \( y \) in terms of the number of kites \( x \) purchased is:
\[ y = 6x + 10 \]
This equation represents the total cost to the customer for purchasing \( x \) kites, including the shipping cost.
