Martin has a combination of 33 quarters and dimes worth a total of $6. Which system of linear equations can be used to find the number of quarters, q, and the number of dimes, d, Martin has?

Question

avi13 · Answer

what is the worth of quartes and dimes individually

avi13 · Answer

one equation is q+d=33
and let cost of q and d is a,b respectively
then other equation is a*q+b*d=6

mathmale · Answer

Notice how avi chose "q" to represent the number of quarters and "d" to represent the number of dimes.
What is the value (in cents) of a quarter?  of a dime?  Let's not use the word "cost" here.
