Answer:
$140
Step-by-step explanation:
If a package of gift cards has a total value of $1050, the total price for 2 gift cards will be 2×$1050 = $2100
If there are 15 in an average set of 2 gift cards, the average cost of the two gift cards will be expressed as;
Total price of 2gift cards/amount of card per group.
Average cost of of 2 gift cards = $2100/15
= $140
Hence the average cost of 2gift cards if there are 15 in a group is $134
