Since 150 is the total and 12 is per week you can actuality do this equation
T= Total,150$ W=Amount saved,12$
150=12*X or 150/12=X
While X = 12.5 Weeks So, the correct answer
is 12.5 Weeks it can be stated As,
12 weeks 3 days 12 hours (X=12.5)
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
