Rosie bought 3 2/5 yards of material for $4.25 per yard. How much did she spend?

$14.45

Step-by-step explanation:

Convert 3 2/5 yards to decimal = 17/5 = 3.4 yards

If 1 yard = $4.25

Then 3.4 yards = x

Cross multiply

x = $4.25 x 3.4

x = $14.45

I hope this helps.

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.
