Talia sells educational software for a yearly salary of $65,000 plus a 2.65% commission on her total sales. If Talia sells $2.5
Bad White [126]

Answer:

$131250

Step-by-step explanation:

Talia's earnings during one year are equal to her base yearly salary ($65000) added to her commission. Now, to know the commission it is necessary to find the 2.65% of her total sales ($2.5 million)

Step 1. Divide the total sales or 2,500,000 by 100 considering this represents the total or 100%

2,500,000 ÷ 100 = 25000

Step 2. Multiply this number by the specific percentage (2.65)

25000 x 2.65 = 66250

Now add the commission and the yearly salary

65000 + 66250 = 131250

Hence, total earnings of Talia were $131250

Rewrite the expression as an algebraic expression in x.<br> tan(sin−1(x))
solmaris [256]
Let tan^{-1} x=\alpha
Then it can be shown by using a right-angled triangle and the rule of Pythagoras that \alpha= tan^{-1} \frac{x}{ \sqrt{1-x^{2}} }
Therefore
tan(sin ^{-1} (x))=\frac{x}{ \sqrt{1-x^{2}} }

The shop declare a discount of 20% and later a discount of 15% after
Oksi-84 [34.3K]
In order to calculate the equivalent discount, consider the principle number is 100, 
Then, 100 - 100 * 0.20 = 100 - 20 = 80
Now, 80 - 80 * 0.15 = 80 - 12 = 68

So, Total discount would be: 100 - 68 = 32%

Hope this helps!
