Answer:
$3.77
Step-by-step explanation:
The formula for the percentage of an amount is : 
To work out the value of the tax you would first need to convert the percentage of 6.5 into a decimal. You can do this by dividing the percentage of 6.5 by 100, this gives you 0.065. This is because percentages are out of 100.
The next step is to multiply 0.065 by the amount of $58, this gives you 3.77. This is because we are working out 6.5% of $58 and so would multiply the decimal by the amount to work that out.
1) Divide 6.5 by 100.
2) Multiply 0.65 by 58.
The first term will be 3 and the sum of the first 9 terms will be 81.
<h3>What is Arithmetic progression?</h3>
The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).
The arithmetic progression has wider use in mathematics for example sum of natural numbers.
Natural number = 1,2,3,4,5,6,7,8...
Given,
Six terms as 10.5
So,
a₆ = 10.5
Common difference(d) = 1.5
The nth term of an AP is given by
= a + (n-1)d
So,
a₆ = a + (6-1)d
10.5 = a + 5(1.5)
a = 3
Now,
The Sum of n terms is given by
S = n/2[2a + (n-1)d]
S = 9/2[6 + 8(1.5)]
S = 81
Hence the first term will be 3 and the sum of 9 terms will be 81.

I believe the solution is
−9 = = 7.1
7+3=4+6 Both numbers equal 10
