The Right Answer:
We need to mutiply all the numbers.
5*-2 = -10
-10*-1 = 10
The Wrong Answer:
(-2)*(-1) gives +2 (a negative number multiplied for another negative gives a positive number).
2*5 = +10
Answer:
the anwser is in the text
Step-by-step explanation:
$30 + $35 = $65
Assuming tax is on whole sale not each item:
$65 * 0.06 (6%) = $3.90 (6% of $65)
$65 + $3.90 = $68.90 ($65 + 6%)
OR
You could combine both of these steps and just use this working:
$65 * 1.06 (106%) = $68.90 (106% of $65)
To find the answer you would multiply 1,300 by .06, which gives you a commission of $78.
Hope this helps!
