for taxes

30%of y

30/100×y=3y/10

=0.3y

freight charges =65

A single tree produces about 2.6 × 10² lb of oxygen each year. The Amazon rainforest has about 3.9 X 10^11 trees.

Ymorist [56]

$(2.6\times10^2) \times (3.9\times10^{11}) = 1.014\times10^{14}$

$1.014\times10^{14}$ <---How much is produced by all the trees in a year.
They want how much each day so divide by 365

$\frac{1.014\times10^{14}}{365} = 2.77808\times10^{11}$
$2.77808\times10^{11}$ <---answer per day
