Problema Solution
Bill has 61.50 and has 4 times as many half dollars as quarters, how many half dollars does he have?
Answer provided by our tutors
let Bill have 'x' half dollars and 'y' quarters.
he has 4 times as many half dollars as quarters
y = 4*x
the total money he has is $61.50 that is
0.5*x + 0.25*y = 61.50
since 1 quarter = 25 cents = $0.25
by solving the system of equations
y = 4*x
0.5*x + 0.25*y = 61.50
we find
x = 41 half dollars
y = 164 quarters
Bill has 41 half dollars.
