No. of quarters #= 19#

No. of dimes #= 23#

#1# quarter is #25# #"cents"# and #1# dime is #10# #"cents"#.

Let the number of quarters #= x#. Then, the number of dimes #= x + 4#. So

#(x*25)+(x+4)*10=$7.05 = "705 cents"#

#25x+10x+40=705#

#35x=665#

#x=665/35=19#

Parker has #19# quarters and #19+4=23# dimes in all.
