7.3 ------ 8.1 8.5 8.9
let us try to find the common difference here using last three terms
8.5-8.1=0.4
8.9-8.5=0.4
so it is clear that common difference is 0.4
so adding 0.4 to 7.3 will give the next term
7.3+0.4=7.7

Answer:
$28.82
Step-by-step explanation:
Since we are adding a 13% tax, we multiply 25.50 by 1 plus .13:
25.50(1 + 0.13)
25.50(1.013)
28.815
Alternatively, we could multiply 25.50 by 0.13 and then add the results:
25.50(0.13) = 3.315
25.50 + 3.315 = 28.815
