Question 1079461
Let {{{ x }}} = the number of shells that Andrew collects
Elliot collects {{{ 1.2x }}} shells
Ryan collects {{{ 1.4x }}} shells
------------------------------
If I say:
{{{ 1.4x = ( 1 + k )*x }}}
{{{ k }}} tells me the decimal that left side
exceeds the right side by
{{{ 1 + k = 1.4 }}}
{{{ k = .4 }}}
{{{ .4*100 = 40 }}}
Ryan collected 40% more shells than Andrew
