From January to June, a company spent $60 per month on office supplies. In July the price of office supplies increased by 15% and remained the same for the rest of the year. How much did the company spend an office supplies for the year

$774

Step-by-step explanation:

We have been given that from January to June, a company spent $60 per month on office supplies. In July the price of office supplies increased by 15% and remained the same for the rest of the year.

Let us find increased cost of supplies as shown below:

There are 6 months from January to June, so cost of supplies on these 6 months would be 6 times $60.

There are 6 months from July to December, so cost of these months would be 6 times $69.

Total cost will be equal to sum of these two amounts.

Therefore, $774 were spent on office supplies.

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.
