Answer

Initial amount $a=350$ Rate of growth $r=75\%$ At $t=5,y=5744.6$.

Work Step by Step

The given expression is $\Rightarrow y=350(1+0.75)^t$ The standard form of the exponential growth function is $y=a(1+r)^t$ Initial amount $a=350$ Rate of growth $r=0.75=75\%$ Substitute $5$ for $t$. $\Rightarrow y=350(1+0.75)^5$ Simplify. $\Rightarrow y=350(1.75)^5$ Evaluate the power. $\Rightarrow y=350(16.4130859375)$ Simplify. $\Rightarrow y=5744.58007813$ Round to the nearest tenth. $\Rightarrow y=5744.6$
