A trip production regression equation was developed using the data given in

Fig. $5\mathrm{.}9.$ The resulting equation is

$O_i=0\mathrm{.}091+0\mathrm{.}735(SIZ{E}_i)+0\mathrm{.}945(A{O}_i)$

where

$O_i=$ total daily trips per household produced $in$ zone $i$

$SIZ{E}_i=$ average household size $in$ zone $i$

$A{O}_i=$ average auto$-$ownership level $in$ zone $i$

Using this equation and the data from the following figure, compute the total daily trip

productions for the given zone.
