Answer: The total cost is $21.64.
Explanation:
Hi, to answer this question, first we have to multiply the price of each pair of earrings (6.38) by the number of pairs bought (3)
Mathematically speaking:
$6.38 x 3 = $19.14
Then we have to add the shipping cost ($2.50)
$19.14+$2.50 = $21.64
The total cost is $21.64.
