2.5= 2 1/2
just do 10/20= .5 so 7.5
8.2= 8 2/10 which simplifies to 8 1/5
2.88=2 <span>22/<span>25
</span></span>
3/6= 7.5
3 1/4= 3.25
i couldn't see the other ones except for also 12
2.1= 2 1/10
<em>If the rate is a constant, the relationship is proportional.</em> (The rate is the constant of porportionality.)
_____
For two or more points on the function curve, divide the dependent variable value by the independent one. If you get the same result in every case, the relationship is porportional.
___
<em>Note</em>
For some non-proportional relationships, it is possible to find points on the graph that will pass the above test. If you suspect the relationship is actually not one of proportionality, try more points. Check also to make sure that (0, 0) is on the curve.
Plan A gives you 6% interest compounded annually so after 4 years
$2000 becomes $2000*(1.06)^4 = $2524.95
Plan B gives you 13% annual simple interest so after 4 years
$2000 becomes $2000*(1+0.13*4) = $3040
so Plan B earns more
