Answer:
Sales amount = $ 300.08
Step-by-step explanation:
Sale amount = selling price + sales tax
Here selling price = $300
sales tax = 8 %
sale amount = 300 + 8%
= 300 +
=( 300 ×100 + 8 )÷100
= (30000 + 8 ) ÷ 100
= 30008 ÷ 100
=$ 300.08
Sales amount = $ 300.08
Answer:
A
Step-by-step explanation:
Recall that for a quadratic equation of the form:
The number of solutions it has can be determined using its discriminant:
Where:
We have the equation:
Thus, <em>a</em> = 2, <em>b</em> = 5, and <em>c</em> = -<em>k</em>.
In order for the equation to have exactly one distinct solution, the discriminant must equal zero. Hence:
Substitute:
Solve for <em>k</em>. Simplify:
Solve:
Thus, our answer is indeed A.
