You did not say how much the cash is worth, so as written, there is not enough information to
solve this problem.
x is the # of Grants, which is the $50 bill, because it bears the image of President Ulysses S. Grant
y is the # of Franklins, which is the $100 bill, because it bears the image of Ben Franklin
x+y = 28 <--- there are 28 bills altogether
50x +100y = Cash Amount
For example, you can have 10 Grants and 14 Franklins, which is 10*50 +14*100 = 500+1400 = 1900
or you can have 20 Grants and 8 Franklins, which is 20*50 + 8*100 = 1000 + 800 = 1800
So as you can see, without this information, there is more than one solution to the problem.
