You'll need to find the effective monthly rate, and then times that by $950 to see how much is charged in interest each month
Effective monthly rate=(1+APR)^1/12)-1

The linear function m=55-8.5b represents the amount m (in dollars) of money that you have after buying b books. Find the domain
Amiraneli [1.4K]

Answer:

The domain is (-∞ , ∞)

The domain is continuous

Step-by-step explanation:

Here, we want to identify the domain of the linear function

The domain in this case can be represented by the set of all real numbers.

When we talk of the domain of a function, we are simply referring to the the range of values between the smallest value on the x-axis and the largest number on the x-axis

Hence, mathematically, we are simply considering the smallest value of b up to the largest value of b in this case. Where b simply represents the number of books

Thus, the domain here will be (-∞ , ∞)

On if the domain is discrete or continuous, we can see that the domain is continuous.

The domain is continuous simply because, the domain we have contains all the values and not some in the set of real numbers. If it had contain only some, then it would have been discrete. But since it contains all, it is continuous

Natasha2012 [34]
We know that
A markup is the ratio of Gross Profit Margin to C<span>ost
</span>so
Markup Percentage = Gross Profit Margin/Unit Cost
Gross Profit Margin=Sales Price – Unit Cost------> $39.99-<span>$6.95----> $33.04
</span>Markup Percentage = $33.04/$6.95------> 4.7540------> 475.40%

the answer is
475.40%
