A percent is just a fraction.
So take your two numbers and make a fraction with them ...  18/30 .

18  is  18/30  of  30 .

Now, to find the percent that's equivalent to  18/30 ,
first do the division:

                     18/30  =  0.6  .

Now, to change a decimal into percent,
move the decimal point two places that way  ==> .

                                     0.6  =  60% .

                                  18  is  60%  of  30 .

An online video store charges $24 please help
mr Goodwill [35]

Answer:

B. 24d + 4; $76

Step-by-step explanation:

Part 1: If the online store charges $24 per DVD, this is the same as saying "24 multiplied by the number of DVDs bought".

It's given that "d" represents the number of DVDs

  • So the first part of the variable expression is: 24d

If the online store also charges an additional $4 per <em>order,</em> that means that it's only $4 extra for the whole order. NOT per DVD you buy.

  • Result: 24d + 4

Part 2: If someone were to buy 3 DVDs, that would mean that d = 3.

To find the total cost, substitute 3 for d into the expression.

  • 24d + 4
  • 24(3) + 4
  • 72 + 4 = 76
  • Result: $76

Steve has 2 and one half cups of flour for one of his recipes requires one 8th cup of flour, what is the maximum number of times
kupik [55]

Answer:

20 times

Step-by-step explanation:

We know that the recipe requires an eighth of a cup of flour (1/8 or 0.125) but in total Steve has 2 and a half, that is (2 1/2 or 2.5). To know the result we must divide the total amount by what is needed for 1 recipe, that is:

2.5 / 0.125 = 20

Which means that Steve with the flour he has can make the same recipe a total of 20 times
