The first step is to find the relationship between the cost and the number of cards in the chart. To do this you need to find a unit price per card. To find this divide the price in any column by the number of cards you will get from the same row.
$13/20 = $0.65 per card.
Now you can set up the equation with the remaining information.
T = 1.077(0.65x) + 5.95
1.077 represents the total amount of the cards (1) plus sales tax (0.077)
x stands for the number of cards you will buy
one time charge of $5.95 is added on at the end
T = 1.077 (0.65 x 280) + 5.95
T = $201.96

Total cost for an order of 280 cards = $201.96
Step-by-step explanation:
Total number of cards to be ordered = 280
This can be done in a way that buy 100 cards twice and 40 cards twice.
280 = 100 + 100 + 40 + 40
So, price in dollars for 100 cards if bought two times = 2 × 65
= $130
And, price in dollars for 40 cards if bought two times = 2 × 26
= $52
Hence, total cost of buying 280 cards = 130 + 52 = $182
Sale tax applied on the price of cards = 7.7%
Total cost after applying sales tax = 182 + 7.7% of 182
⇒ Total cost = 182 + 0.077 × 182
⇒ Total cost = 182 + 14.014
⇒ Total cost = $196.014
Also, One time mailing fee of $5.95 is also applied on the order.
⇒ Total cost for an order of 280 cards = 196.014 + 5.95
= $201.96
