MHB Word Problem: Application Of Linear Equations (Typo In Textbook?)

AI Thread Summary
The discussion centers on the confusion between two statements regarding the relationship between the number of dimes and nickels. The first statement, "The number of dimes is 5 times more than twice the number of nickels," translates to d = 5 * 2n, while the second, "The number of dimes is 5 more than twice the number of nickels," translates to d = 2n + 5. Participants note that using the first equation results in a decimal, whereas the second yields a whole number, suggesting a potential typo in the original problem. The consensus is that the phrasing of the problem may indeed be incorrect. Clarification on this issue is needed for accurate problem-solving.

Is there a difference between the following statement

"The number of dimes is 5 times more than twice the number of nickels" and "The number of dimes is 5 more than twice number of nickels"?

The 5 times more... and the 5 more than... confuses me. Please clarify this for me. Thanks!

Hello the orginal problem where I get that statement from is this

The soda machine contains $3.00 in nickels and dimes. If the number of dimes is 5 times more than twice the number of nickels, how manay coins of each type are there?

When I used d=5*2n, I get a decimal number. But when I use d = 5+2n I get an exact answer. Do yout think the problem has typo error?
 
Re: Word problem

It certainly appears that way. My results are the same as the results you described.
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...

Thread 'Six Pencil Puzzle'

Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.
