Answer:
x=6, x= -5
Step-by-step explanation:
Factor the equation
x^2 - x - 30 = 0 ----> (x-6)(x+5)=0
Next find the solution by setting those in the paranthesis equal to zero.
x-6=0 ----> x= 6
x+5=0 ----> x= -5
Answer: $4.52
Step-by-step explanation:
From the question, sales tax rate is $8.25 per $100, this means that for every $100 item sold, $8.25 will be paid as sales tax.
Sales tax for 54.80 = x
Step 2: write the equation as;

$8. 25/ 100 = $0.0825
Step 3: determine the sales tax on $1 item, that is if sales tax $1 item = $0.0825
Sales tax for $54.80 item will be 0.0825 x 54.80
= $4.52
