No it is not a proportional relationship. If you remember y=mx+b, and your equation is y=2x+5. If the equation has a "b", in this case your B is 5, it is non-proportional.
<h2><em>James has $9
</em></h2><h2><em>Priya has $10.80
</em></h2><h2><em>Siobhan has $9.18
</em></h2><h2><em>because 9*20% is 1.8 so add that to 9 to get 10.80 then times 10.80 by 15% to get 1.62 so you subtract 1.62 from 10.80 to get $9.18 </em></h2>
