Question 207419
Let {{{p}}}= the original price of coffee per pound
{{{1.25p}}} will be the new price of coffee per pound
Let {{{c}}} = consumption in pounds originally
Let {{{a}}} = the fraction of new consumption allowed
---------------------
The equation I want to be true is:
{{{pc = 1.25*p*a*c}}}
divide both sides by {{{pc}}}
{{{1 = 1.25a}}}
{{{a = 4/5}}}
If 4/5 of the previous consumption is allowed, then
the past consumption must be reduced by {{{1/5}}} answer
