An item sells for $30 and is on sale for 15% off and the sales tax is 8.2%. What is the final cost to the nearest cent? (Calcula
mestny [16]

Answer:

$27.59

Step-by-step explanation:

You multiply 30 dollars by 0.85 (1-0.15, with the 0.15 being for the 15 percent off). Which gets you to $25.50, and you then multiply it by 1.082 (the 1.082 being the tax, and the .082 part equating to the 8.2% tax percentage).

Emmanuel added two integers Which condition will always give Emmanuel a negative solution when he adds two integers? Both intege
alexgriva [62]

Both integers have negative values

Explanation

Let

x and y represents the number

so, the options are

\begin{gathered} +\text{   +     +} \\ +\text{  +      -} \\ -\text{     +     +} \\ -\text{   +-} \end{gathered}

a) Both integers have negative values Both integers

-x-y=-(x+y)\rightarrow you\text{ will always get a negative number}

b) Both integers have positive values

x+y=+\text{  +  += you will always get a positive number}

c)One integer has a positive value, and one integer has a negative value

\begin{gathered} -x+y\text{  or x-y} \\ the\text{ sign of the result depends on the greates absolute value, it means the answer will have the same of the bigger number( absolute value)} \end{gathered}

d)The values of the two integers are opposites​

as the point C , the sign depends on the bigger number

for example

\begin{gathered} 8-5=3\text{ positive because 8 is the bigger} \\ 5-8=-3\text{ negative because (-8) is has the bigger absolute value} \end{gathered}

so, the answer is Both integers have negative values

I hope this helps you
