Answer:
$560.00
Step-by-step explanation:
Let b represent Tony's average daily balance. The finance charge is computed from ...
... finance charge = 2.25% × b
We can fill in the given value and divide by the coefficient of b.
... $12.60 = 0.0225b
... $12.60/0.0225 = b = $560.00
Tony's average daily balance was $560.00.
Answer:
Two consecutive integers are of the form
x and x + 1
Their product is equal to 56
x(x + 1) = 56
Solve and find the two numbers x and x + 1. The above equation may be written as follows
x2 + x - 56 = 0
Factor and solve
(x - 7)(x + 8) = 0
solutions: x = 7 , x = -8
x= - 8 is not valid since the number sought must be positive. Hence
x = 7 and x + 1 = 8 are the two consecutive numbers.
Step-by-step explanation:
Hope this is correct and hope it helps x
