Can i please get some help on this?

Answer:

Step-by-step explanation:

The slope of b is 5.5 whereas the slope for the other three graphs are 5, so B is different from the rest.

A. (4, 0.8), so by rise over run, the slope is 4/0.8=5.

B. (55, 10), so 55/10=5.5.

C. (20, 4), so 20/4=5.

D. (50, 10), so 50/10=5.

Since B is the only graph with a slope of 5.5 and the other graphs have a slope of 5, the answer is B.

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.
