A printing service charges a set up fee of 11.00 for each order and 10 cents more for each copy . the totsl cost, C (in dollars), for an order of x copies is given by the following . C= 11.00+ 0.10x What is the total cost for an order of 20 copies ?

$13.00

Step-by-step explanation:

First, you plug in your x value for copies into the equation C=11.00+0.10x to get a starting equation of x=11.00+0.10(20). Since 0.10 is equivalent to 1/10, it's easy to compute (1/10)(20)=2. You now have an equation of C=11.00+2.00 to get C=13.00. Therefore, the total cost for an order of 20 copies is 13 dollars (and 0 cents).

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
