Answer:
he should sell it for ₹8800 to make a profit of 10%
Step-by-step explanation:
if he lost 15% despite selling at a price of ₹6800
that means he sold it for 100%-15%=85%
85% - ₹6800
1% - ₹80
to make a profit of about 10% means 100%+10 which is 110%
110% --> 110 * ₹80
--> ₹8800
<span>To simplify the polynomial 4x^2 + 4 - 5x + x - 2x^2 + 8, first rewrite it to put all the like terms next to one another: 4x^2 - 2x^2 - 5x + x + 4 + 8. Then, add together these like terms: 2x^2 - 4x + 12. So, the correct answer will be the last option. </span>
The expected value of a distribution is considered as a mean, or average, for a probability distribution. It represents the center of the possible values of a variable. That doesn't necessarily mean it would be one of the possible values of x.
5% = 0.05
50 x 0.05 = $2.50
Total tax will be $2.50
Total amount he will pay = 50 + 2.50 = $52.50
