Question 122212
Let d=# of dimes, q=# of quarters, s=sum of your money



Since a dime is 10 cents, it is $0.10 by conversion from cents to dollars. Also a quarter, which is 25 cents, is $0.25



So the sum of your money would be {{{s=0.1d+0.25q}}}


Since you have at least $30, this means that the sum of your money is greater than $30 like this:


{{{s>30}}}




{{{0.1d+0.25q>30}}} Now plug in {{{s=0.1d+0.25q}}}




Answer:



So the inequality that represents this problem is 



{{{0.1d+0.25q>30}}}
