Question 1099581
Let {{{ x }}} = ounces of mixture A to be added
{{{ .12x }}} = ounces of baking soda in mixture A
{{{ .25*130 = 32.5 }}} = ounces of baking soda in mixture B
------------------------------------------------------
{{{ .12x + 32.5 = 52 }}}
{{{ .12x = 19.5 }}}
{{{ x = 162.5 }}}
Add 162.5 ounces of mixture A
---------------------------------
check answer :
{{{ ( .12x + 32.5 ) / ( x + 130 ) = 52/( x + 130 ) }}}
{{{ ( 19.5 + 32.5 ) / 162.5 = 52/162.5 }}}
{{{ 52/162.5 = 52/162.5 }}}
{{{ .32 = .32 }}}
So you end up with a 32% mixture
( not required by problem )
OK
