$47.25

Step-by-step explanation:

Xander bought 3 shirts for $15.00 each

Total cost of the three shirts

= $15.00 x 3

= $45

A 5% tax fee was added to the cost

That’s

Tax = 5% of total cost

= 5% of $45

= 5/100 x $45

= 0.05 x $45

= $2.25

Therefore

Amount paid by Xander

= $45 + $2.25

= $47.25

Xander paid $47.25 for the shirts

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
