In the exponential growth function y = 235(1.15)^x, what is the
sweet-ann [11.9K]

Answer: Growth factor will be 0.15 and percent increase will be 15%.

Step-by-step explanation:

Since we have given that

the exponential growth function

y=235(1.15)^x

1) We need to find the growth factor :

As we know the formula for "Compound Interest ":

A=P(1+\frac{r}{100})^x

If we compare the formula with our given equation, we get

1+\frac{r}{100}=1.15\\\\\frac{r}{100}=1.15-1\\\\\frac{r}{100}=0.15\\\\r=0.15\times 100\\\\r=15

So, the growth factor is at the rate of 0.15.

2) Percent increase will be

0.15=\frac{15}{100}\times 100\\\\=15\%

Hence, growth factor will be 0.15 and percent increase will be 15%.

A pair of tires is $216, so at that rate 4 tires would be $432. The managers special is $380 so $432-$380=$52 savings for 4. $52\4=$13 savings per tire.
