Ответ:
$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
