Lola has twice as many quartes and half as many nickels as does ellen. ellen
has $6.30 in quarters and nickels and has 6 less nickels than quarters. how much money does lola have?
you are supposed to put it with quarters and nickels.

So
eq=ellen's quarters
en=ellens's nickles
lq=lola's quarters
ln=lola's nickles
lq/2=eq or lq=2(eq)
2(ln)=en or ln=en/2
en+eq=$6.30 or 630 cents
en+6nickles=eq
so nickle=5 so
5*6=30
630-30=600
number of nicles=number of quarters of  lola=600
nickle+quater=30
600/30=20
20 quarters
20+6=26 nickles
elen has 20 quarters and 26 nickles

20 times 2=40 quarters
26 divided by 2=13 nickles
lola has 40 quarters and 13 nickles

40 times 25=1000 cents in quarters
13 times 5=65 cents in nickles
1000+65=1065 cents or $10.65=lola's money
