Aprinter will produce 80 wedding invitations for $210. the price to produce 120 invitations is $290. the printer uses a linear function to determine the price for producing different amounts of invitations. how much will the printer charge to produce 60 invitations?
a)$120.00
b)$145.00
c)$157.50
d)$170.00

 Option 'D' is correct.

Step-by-step explanation:

Let the number of wedding invitations be represented by x axis.

Let the cost of wedding invitations be represented by y-axis.

So, At cost of $210, a printer will produce 80 wedding invitations.

At cost of $290, a printer will produce 120 wedding invitations.

So, we have (80,210) and (120,290)

So, our equation of slope will become:

We need to find the cost of 60 (= x) invitations:

Hence, Option 'D' is correct.

The printer charge is $170 to produce 60 invitations.

Step-by-step explanation:

A printer will produce 80 wedding invitations for $210

The price to produce 120 invitations is $290.

We will use two point slope form

Formula :

Substitute the values :

Now we are supposed to find the printer charge to produce 60 invitations

Substitute x = 60

Hence the printer charge is $170 to produce 60 invitations.

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.
