Answer:

$12

Step-by-step explanation:

assuming that the cost of delivery is constant irrespective of the number ordered

Let the cost of sandwich be x

First office

$33=4x+c where c is the cost of delivery

Second office

$61=8x+c

These two are simultaneous equation. Subtracting the equation of first office from the second office we obtain

4x=28

Therefore, x=28/4=7

The cost of delivery is 33-(4*7)=33-28=5

Therefore, one sandwich plus delivery costs 7+5=$12

Suppose the sample space for a probability experiment has 8 elements. If elements from the sample are selected without replaceme
Gwar [14]

Answer: Number of ways =\dfrac{8!}{8!0!}\ or \ 1

Step-by-step explanation:

When there is no replacement , we use combination to find the number of ways to choose things.

Number of ways to choose r things out of  ( with out replacement) = ^nC_r=\dfrac{n!}{r!(n-r)!}

The number of ways to choose  8 things = ^8C_8=\dfrac{8!}{8!(8-8)!}=\dfrac{1}{0!}=1  [\because 0!=1]

Hence,  Number of ways =\dfrac{8!}{8!0!}\ or \ 1

Carrie is driving to a friend’s house for the weekend. The friend lives in a town 160 mi. away. So far, Carrie has driven 64 mi.
ankoles [38]

Divide the amount she drove by the total amount she needs to drive, them multiply that answer by 100 to make it a percent. This will give you the percentage she drove. To find the percentage she has left,, subtract from 100%.


64 / 160 = 0.4

0.4 * 100 = 40%  (  percent she has already driven)


100% - 40% = 60% left.

Clarence sells yearly subscriptions to a particular magazine. He sells at least 10 and no more than 25 subscriptions each week.
kobusy [5.1K]

We have that Clarence sells yearly subscriptions to a particular magazine.

He sells at least 10 and not more than 25 subscriptions each week.

The function f(t) = 48t represents the amount of money earned for selling t subscriptions each week.

So;

10 ≤ t ≤ 25

f(t) therefore is 48(10) ≤ f(t) ≤ 48(25)

This gives: 480 ≤ f(t) ≤ 1200

So the amount of money earned f(t) for selling t subscriptions each week is all multiples of 48 between 480 and 1200, inclusive.
