Answer:
Step-by-step explanation:
Let's denote the number of necklaces Chris bought as �n.
Each necklace costs $14, so the total cost of �n necklaces before applying the coupon is 14�
14n dollars.
After using the $15 off coupon, the total cost becomes $69. Therefore, we can write the equation:
14�−15=69
14n−15=69
This equation represents the total cost of the necklaces minus the $15 discount being equal to the final cost of $69.
