5 hrs

to work this out you need to do this: 

Apple:

$70×2hrs+$25= $165

$70×3hrs+$25=$235

$70×4hrs+$25=$305

$70×5hrs+$25=$375

Local tech shop:

$65×2hr+$50=$180

$65×3hr+$50=$245

$65×4hr+$50=$310

$65×5hr+$50=$375

Now, if you go back and check both the costs you'll see that they are similar after 5 hours.

Unsure of what you mean by "y1."

If you wish to solve this eqn for y, do this:
-5y = - 3x + 20,
-3x + 20
y = ---------------- = (3/5)x - 4 (answer)
-5

Using the binomial distribution, it is found that the probability that exactly 36 of them buy a product is of 0.044.

For each first-time visitor, there are only two possible outcomes, either they buy a product, or they do not. The probability of a first-time visitor buying a product is independent of any other first-time visitor, hence the binomial distribution is used to solve this question.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
