Rolex buys computer disks at a price of 4 for $5 and sells them at a price of 3 for $5. How many computer disks must he sell to

Lina20 [59]

Given that Rolex buys computer disks at a price of 4 for $5 .

That means cost price of 1 disk = 5/4

Given that Rolex sells them at a price of 3 for $5.

That means selling price of 1 disk = 5/3

Profit on 1 disk = selling price - cost price

Profit on 1 disk $= \frac{5}{3}-\frac{5}{4}$

Profit on 1 disk $= \frac{5}{3}\cdot\frac{4}{4}-\frac{5}{4}\cdot\frac{3}{3}$

Profit on 1 disk $= \frac{20}{12}-\frac{15}{12}$

Profit on 1 disk $= \frac{5}{12}$

Now we have to find how many disk to be sold to get the profit $100

so we just divide $100 by profit on 1 disk

$\frac{100}{\left(\frac{5}{12}\right)} = 100\cdot\frac{12}{5} = 240$

Hence final answer is 240 disks.

Kruka [31]

Answer:

Step-by-step explanation:

2(9a - 6) = 2*9a - 2*6 = 18a - 12

Yes, it is equivalent.

6*(3a-2) = 6*3a - 6*2 = 18a - 12

Yes, it is equivalent.

-3(6a+4)= -3*6a + 4*(-3) = -18a - 12

No, not equivalent

3(6a+4) = 3*6a + 3*4 = 18a + 12

No, not equivalent

-3(4-6a) = -3*4 - 6a*(-3 ) = -12 + 18a = 18a - 12

Yes, it is equivalent.
