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

[NotaMathPerson]

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!

Re: Word problem

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

d = 5 * 2n

"The number of dimes is 5 more than twice number of nickels"

d = 2n + 5

Re: Word problem

d = 5 * 2n
d = 2n + 5

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.
