If 8 cakes cost $62.40, how much would 3 cakes cost?
Ilya [14]

Answer:

<h2><em><u>$23.40 </u></em></h2>

Step-by-step explanation:

<em><u>Given,</u></em>

Cost price of 8 cakes = $62.40

<em><u>So,</u></em>

Cost price of 1 cake = $ \frac{62.40}{8}

<em><u>Therefore,</u></em>

Cost price of 3 cakes

= $(\frac{62.40}{8} × 3)

  • <em>[On dividing 62.40 by 8]</em>

= $(7.80 × 3)

  • <em>[On multiplying]</em>

= $23.40

<em><u>Hence,</u></em>

<em><u>The required cost of 3 cakes is $23.40 (Ans)</u></em>

Integral of ln times cube root x dx
zvonat [6]
If u = ln(x^(1/3))
then by the chain rule
du = [1/x^(1/3)] * (1/3)x^(-2/3) dx = (1/3)(1/x) dx. 
You could get there faster by noting that
 ln(x^(1/3)) = (1/3) ln(x), so du = (1/3) dx/x
