I am thinking your answer is 78 students. You do 1/5 times 390. And I think the the part about the dog is just extra information.

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.

susan figure the slope of the line passing through the points (4,19) amd (7,28) to be 1/3. the teacher believes susan is wrong.

melamori03 [73]

For (x1,y1) and (x2,y2)
slope=(y2-y1)/(x2-x1)

(4,19)
(7,28)

slope=(28-19)/(7-4)=9/3=3/1=3
