I need help and this is giving out 10 points.

One pound costs 1.26, two costs 1.47, three costs 1.68, and four costs 1.89. So we calculate how much it increases in each pound.

1.26 + 21 = 1.47

1.47 + 21 = 1.68

1.68 + 21 = 1.89

1.89 + 21 = 2.10

2.10 + 21 = 2.31

2.31 + 21 = 2.52

2.52 + 21 = 2.73

8 pounds cost: 2.73

So I pay $ 2.73 for 8 pounds.

i can't solve unless i know what the line is
