Question 701359
Because the recipe that serves 8 people requires 2 cups of sugar, a single person uses {{{ 2/8=.25 }}} cup of sugar. So if y is the amount of sugar required to prepare the recipe for a group of x people, then {{{ y=.25*x }}}. So if {{{ x=19 }}} is the size of the group of people for which we need an amount of sugar to be denoted by the variable y, then {{{ y=.25*19 }}}, so {{{ y=4.75 }}} cups of sugar.
