Question 1047025

recall:

Growth:

{{{y=a(1+r)^x }}} where {{{r}}} is rate 

Decay:
{{{y=a(1-r)^x  }}}

you have: 
1. {{{y = 1.7 (1.06)x}}}-> means growth, {{{(1+r)=1.06 }}} ->{{{1.06=1+0.06 }}} and {{{0.06}}}is growth rate of {{{6}}}%
so, this one matches a.	rate of growth {{{6}}}%
	
2. {{{y = 1.7 (0.93)x}}} -> means decay, {{{(1-r)=0.93 }}} ->{{{r=1-0.93 }}} and {{{0.07}}}is decay rate of {{{7}}}%
		
this one matches b. rate of decay {{{7}}}%


3. {{{y = 250 (1.08)x}}}-> means growth, {{{(1+r)=1.08 }}}  and {{{0.08}}}is growth rate of {{{8}}}%
so, this one matches
	c.	Rate of growth {{{8}}}%


4. {{{y = 250 (0.925)x }}}  -> means decay, {{{(1-r)=0.925 }}} ->{{{r=1-0.925 }}} and {{{0.075}}}is decay rate of {{{7.5}}}%
		
this one matches

d.	Rate of decay {{{7.5}}}%
