Tracy goes on a 3 day and night school band trip. There is no cost for travel and each band member only pays half the cost of the hotel room. However, each person is responsible for the cost of their own meals. His portion of the hotel bill is $49 per night and Tracy leaves a 10% tip for the maid service. Before tax, Tracy spends $32 per day on eating out plus 15% of this amount in tips. If Tracy spends a total of $280.74 on the band trip, what percent tax was Tracy charged on his food?
a.
6%
b.
7%
c.
8%
d.
9%

Answers

Answer:

Step-by-step explanation:

The service tax that is given on the food each day is 9 %.

What does service tax mean?

The government levies a service tax on particular service transactions carried out by the service provider. Suppose x% service tax is levied on a good on $n then the total amount that is to be paid is $(n(1+x/100)).

How to solve the problem?

Let the percent service tax that is charged on food be x%.

The situation is The total expenditure is $280.74 which is $49 per day on the hotel bill for 3 days on which a 10% tip was given for the maid services each day.

$32 was spent each day on food plus 15% of that amount was given as a tip each day.

And x% of $32 was given on tax.

Then, the equation that best represents the given situation is

280.74/3=49+(0.10)(49)+32+(0.15)(32)+(x/100)(32)

Then 93.58=90.7+(32)(x/100)

⇒32x=2.88×100

⇒x=288/32=9%

Thus, the service tax that is charged on the food each day is 9 %.

A store buys 8 sweaters for $72 and sells them for $288. How many profit does the store make per sweater?

Answers

Answer:

$27 per sweater

Step-by-step explanation:

To solve this, all we need to do is subtract the profit made by the amount the store bought the sweaters for:

288 - 72 = 216

Now, we can divide this number by 8 to find how much profit the store made per sweater:

216 / 8 = 27

So, the store made a profit of $27 per sweater.

Hope this helps :)

10 ounces = 1 ounce

2.50 x

to get to the unit rate, you can see that you divided 10 from 10 ounces so you would do the same to the bottom ...

2.50/10 which is equal to 0.25.

Express each of these system specifications using predicates, quantifiers, and logical connectives, if necessary.

a. At least one console must be accessible during every fault condition.
b. The e-mail address of every user can be retrieved whenever the archive contains at least one message sent by every user on the system.
c. For every security breach there is at least one mecha- nism that can detect that breach if and only if there is a process that has not been compromised.
d. There are at least two paths connecting every two dis- tinct endpoints on the network.
e. No one knows the password of every user on the sys- tem except for the system administrator, who knows all passwords.

Answers

The system specification with predicates, quantifiers, and logical connectives are:

a. ∃C(x) ∀F(y) such that if F(y) is true, C(x) is true.

b. ∀U(x) (∃M(y) if ∀U(z), ∃M(w) is true, then E(x) is true).

c. ∀B(x) (∃D(y) D(y) can detect B(x) ↔ (∃P(z) ¬P(z) is true)).

d. ∀E(x, y) (∃P(z, w) and ∃P(u, v) such that P(z, w) and P(u, v) connect

E(x, y)).

e. ∀U(x) (¬P(x) is true, except for the system administrator who knows all passwords: ∀U(y) P(y) if y is the system administrator).

We have,

Let C(x) be the predicate "x is a console" and F(x) be the predicate "x is a fault condition".
