It would be 13.50 because 50% off of 18$ is 9$ but it’s not 50% off itS 25% off so If you take the 50% Off price of 9$ and add 4.50 (One more 1/4th) you get $13.50
(1-z) can combine with other coupons
3kg+2kg=5kg
5/$3.25=0.65
price per kg=0.65
We know that the form of line passing through point (x₀ , y₀) and having slope m is : y - y₀ = m(x - x₀)
Here the line passes through the point (-2 ,9)
x₀ = -2 and y₀ = 9 and Given : Slope(m) = -14
Equation of the line :
⇒ y - 9 = -14(x + 2)
3rd Option is the Answer
Answer:
rs 38.
Step-by-step explanation:
Total cost of the 80 books = 80*30 = rs 2400.
He had 60 books to sell and made a 5% loss.
Thus his income from these books was 2400 - 0.05*2400 = rs 2280.
So the selling price of each book was 2280 / 60 = rs 38.
