Answer:
The price before tax was $110
Step-by-step explanation:
Here the price paid totals $129.25, including b (the pre-tax price) an 17.5% of b: b + 0.175b = $129.25. Combining the b terms, we get:
1.175b = $129.25. Solving for b by dividing both sides by 1.175, we get
b = $110. The price before tax was $110.

The sum of first 20 terms of Arithmetic Series is 650 if the first term is 4 and the common difference is 3.
Step-by-step explanation:
First Term (a) = 4
Common difference (d) = 3
The number of term (n) = 20
The sum of an Arithmetic series of (n) number of terms, with first term (a) and the common difference (d) is equal to
Sum = (n/2) * ( 2 * a + (n -1) * d)
So putting the values of a,d, n
Sum = ( 20/2) * ( 2 * 4 + (20 -1) *3 )
Sum = (10) * ( 8 + 19 * 3)
Sum = 10 * ( 8 + 57)
Sum = 10 * 65 = 650
Hence the sum of first 20 terms of Arithmetic Series is 650 if the first term is 4 and the common difference is 3.
