i think the answer is d (the last choice)

$12.64

Step-by-step explanation:

From the question, we are informed that Rachel finished a meal at a diner and received a bill for $10.99 and that she charged the bill along with a 15 percent gratuity to her credit card.

The total amount she charged to her credit card will then be:

= $10.99 + (15% × $10.99)

= $10.99 + (0.15 × $10.99)

= $10.99 + $1.6485

= $12.6385

= $12.64
