Question 1029149
The minimum number of coins will
make the greatest use of quarters
18 quarters = {{{ 18*.25 = 4.5 }}} 4.50
Too many quarters -only a nickel left
17 quarters = {{{ 17*.25 = 4.25 }}}
{{{ 4.25 + .3 = 4.55 }}}
17 quarters and 3 dimes is minimum number of coins
--------------------------
The maximum number of coins will
make the greatest use of dimes
44 dimes = {{{ 44*.1 = 4.4 }}} 4.40
Can't use this -only 15 cents left
43 dimes = {{{ 43*.1 = 4.3 }}} 4.30
{{{ 4.55 - 4.3 = .25 }}}
43 dimes and 1 quarter is the maximum number of coins
