Question

cell phone call costs $0.07 per minute for the first 25 minutes and $0.10 per minute for each additional minute.how much would a 47 minute call cost

Answer 1

47 minutes is broken down into 25 minutes + (47-25=22)minutes.

The first 25 are charged at 7c/min for a total of 7 x 25 = 175c
The next 22 minutes are charged at 10c/min for a total of 10 x 22 = 220c

The total cost is therefore,

(175 + 220)c = 395c

which is $3.95

Answer 2

0.07*25+0.10*(47-25)=1.75+2.2=3.95

Answer 3

Peter is distributing pamphlets about dog care and samples of dog biscuits.The dog biscuits come in packages of 12 and the pamphlets are in paackages of 20.What is the smallest number of samples and pamphlets he needs to distribute without having any left over? How many packages of dog biscuits and pamphlets will peter need?

Answer 4

Let the number of dog biscuit packages be D and the number of pamphlet packages, P. The number of dog biscuits distributed will then be 12D (12 biscuits per package times the number of packages) and the number of pamphlets will be 20P by similar reasoning. We want a situation where\[12D=20P\]since that means the number of dog biscuits distributed will equal the number of pamphlets. We can simplify that expression as\[3D=5P\]after dividing by a common factor of 4.

Answer 5

Well, if D=5 and P=3, the equation will be equal.

Answer 6

Also, for all integers D less than 5, we cannot find an integer for P that will make the statement true, so D=5 is the minimum we can have, and therefore, P=3 the minimum for pamphlet packages.

Answer 7

5 dog biscuit packages;
3 pamphlet packages.

Answer 8

How many packages of d and p will peter need though?

Answer 14

what is the smallest number of samples and pamphlets he needs to distribute without having any left over??????????

Answer 15

He has to use 5 dog biscuit samples (each has 12 biscuits, which will mean he'll get through 60 biscuits) and 3 pamphlet packages (each has 20 pamphlets, which will mean he'll get through 60 pamphlets). 60 biscuits, 60 pamphlets = no waste.
