Ilya [14]

Question is not proper, Proper question is given below;

For a birthday party, Mr. Perkins orders 8 chocolate chip cookies and 16 sugar cookies. Each cookie is the same price. He also picks up a cupcake for himself, which costs $2.75. The total bill is $44.03. What is the cost of a cookie?

Answer:

The Cost of the cookie will be $1.72.

Step-by-step explanation:

Given:

Mr Perkins orders 8 chocolate chip cookies and 16 sugar cookies.

Since cost of both the cookies are same then Let us assume the cost of cookies be 'x'.

Total cost of the cookies = $(8 + 16)x = 24x$

Cost of Cup cakes = $2.75.

Total bill he pays = $44.03

We need to find the cost of each cookies.

Now we know that Total bill he pays is equal to sum of Cost of cookies and Cost of Cup cakes he bought.

Framing in equation form we get;

$44.03 = 24x + 2.75$

Now Subtracting both side by 2.75 using Subtraction property we get;

$2.75+24x-2.75 = 44.03 - 2.75\\\\24x = 41.28$

Now Dividing both side by 24 using Division property we get;

$\frac{24x}{24} = \frac{41.28}{24}\\\\x=1.72$

Hence The Cost of the cookie will be $1.72.

A certain taxi driver charges a rate of r cents per person per mile. How much money, in dollars, would it cost three people to t

Anika [276]

Answer:

It would cost ( 3xr/200) dollars to three people to travel x miles.

Step-by-step explanation:

Here, according to the question:

The rate of the taxi fare = r cents per person per mile

The total number of people travelling = 3 friends

Each person travels x miles.

So, the total distance traveled by 3 friends

= 3 ( Distance traveled by 1 friend) = (3 x) miles

Now, as each mile costs r cents.

So, the cost of travelling (3 x) miles = ( 3 x) (r) cents .... (1)

Also, 100 cents = $ 1

So, 1 cent = (1/100) dollars

⇒ r cents = (r/100) dollars

So, the cost of travelling (3 x) miles = ( 3xr/100) dollars .... (2)

Now, If he gives them a 50% DISCOUNT.

Then the cost of travelling (3 x) miles = ( 3xr/ 2 x 100) dollars

= ( 3xr/200) dollars

Hence,it would cost ( 3xr/200) dollars to three people to travel x miles.

Nick, Joey, Beki, and Carmen ran in the town's annual road race. Each person had a different jersey number {2, 13, 20, and 34} a

erastova [34]

Answer:

Beki's jersey number is 34. She last 12 minutes

Nick's jersey number is 20. He last 10 minutes

Carmen's jersey number is 2. She last 14 minutes

Joey's jersey number is 13. He last 11 minutes

Step-by-step explanation:

• The sum of the digits on Beki's jersey number is 7. Therefore, Beki's number is necessarily 34 (3+4 = 7)

• Nick's jersey number is 18 greater than Carmen's. Therefore, Nick's jersey number is 20 and Carmen's jersey number is 2 (2 + 18 = 20). If Carmen's jersey number was 13, 13+18 = 31 which is not included in the options. If it was 20, 20+18 = 38 is not included either.

• From previous items, Joey's jersey number is 13

• The runner with the lowest jersey number also ran the slowest time. Therefore, Carmen last 14 minutes

• Nick finished exactly 2 minutes faster than Beki. Therefore, Nick's time is 10 minutes and Beki's time is 12 minutes, because from the remaining options (10, 11 and 12) this is the only combination 2 minutes apart.

• From previous items, Joey's time is 11 minutes
