Step-by-step explanation:

Given: A hat salesman earns a commission of 15% of all hat sales. Yesterday he sold 3 hats for $90 each and 4 hats for $50 each.

Let's find the total sale value of the hat yesterday.

Total sale = 3*$90 + 4*$50

= $270 + $200

Total sale of the hat = $470.

The salesman earns 15% commission the total sale value.

15% = 15/100 = 0.15

commission = 15% of $470

= 0.15*470

= $70.50

He earned $70.50 as commission.

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.
