The system of equation which represent the scenario is;

x + y = 42

x + y = 420.13x + 0.18y = 6.66

<h3>Simultaneous equation</h3>

let

  • number of 13 cent stamps = x
  • number of 18 cent stamps = y
  • Total cost of the stamps = $6.66
  • Total number of stamps = 42

x + y = 42

x + y = 420.13x + 0.18y = 6.66

Therefore, the equation which represent the problem is;

x + y = 42

0.13x + 0.18y = 6.66

The value of track is given by:
V(x)=32500(0.92)^x
when x=2
V(2)=32500(0.92)^2=$27508

when x=3
V(3)=32500(0.92)^3=$25,307.36

Difference in values will be:
27508-25307.36
