Jenna has 35 Quarters and 15 Dimes.
Let
x--------> the number
we know that
x+(1/x)=65/28---------> x+1/x=65/28-----> multiply by x
x²+1=65/28*x-----> x²-(65/28)*x+1=0
using a graph tool----> to resolve the second order equation
see the attached figure
the solution is
x=1.75-----> 1 3/4----> (4*1+3)//4----> 7/4
so
7/4+4/7----> (7*7+4*4)/28----> (49+16)/28----> 65/28----> is correct
the answer isthe number is 7/4
