Mobile data traffic. Table $5$ estimates of mobile data traffic, in exabytes $\left({10}^{18}\text{bytes}\right)$ per month, for years from $2015$ to $2020$.

(A) Let $x$ represent the number of years since $2015$ and find an exponential regression model $\left(y=a{b}^x\right)$ for the mobile data traffic.

(B) Use the model to estimate the mobile data traffic in $2025$.
