Answer: (13, -8)
Step-by-step explanation:
Subtract 5 from -3
Add 5 to 8
Let the number of rows be x
rows = x
seats in each row = x + 20
total seats = 1344
x (x + 20) = 1344
x^2 + 20x - 1344 = 0
(x + 48)(x - 28) = 0
x = -48 (rejected, answer cannot be negative) or x = 28
Therefore,
x = 28
x + 20 = 48
Check:
Row = 28
Numbers of seat per row = 28 + 20 = 48
28 x 48 = 1344 (Correct)
Ans:There are 48 seats per row
Step-by-step explanation:
Price of Jeans = $78.35
30% coupon = 30% × $78.35 = $23.51

1% local option tax = 1% × $78.35 = $0.78
Total cost of jeans = $78.35 - $23.51 + $4.70 + $0.78 = $60.32
