Question 369399
the interest percentages are spurious information ___ probably thrown in to cause confusion


the key is the ratio of the amounts of the two investments
___ we don't know the amounts , but we do know the ratio
___ so we put in a constant (fudge factor) and build an equation


7c = 5c + 500 ___ the ratio is 7 to 5 , with the larger amount being 500 more


2c = 500 ___ c = 250


so the two amounts are 1750 and 1250 (250 multiplied by 7 and 5, respectively)
