The cost for a business to make greeting cards can be divided into one-time cost (e.g., a printing machine) and repeated costs (e.g., ink and paper). Suppose the total cost to make 300 cards is $900.00, and the total cost to ma 650 cards is $1,600.00. What is the total cost to make 1,000 cards? Round your answer to the nearest dollar.

2,100.00
2300.00
2500.00
3000.00

Answers

If you divide 1,600.00 by 650 you get a long decimal, which you could round off to get you 2.5 now if you multiply 1000 by 2.5 you get a total of 2500.00
2500.00 would be your answer!! good luck

Pete wants to treat several friends to the baseball game. he has a budget of $110. tikets are $8. he will spend $20 on parking how many friends can he afford to take without going over his budget?

Answers

Answer:

He can take 11 friends.

Step-by-step explanation:

110 - 20 = 90

Then you do simple math, how many times can 8 go into 90? Well, 8 times 10 is 80, so add 8 more and you have 88 (Which is 8 times 11).

90 - 88 = 2, so you can put in anymore.

Answers

Answer:

Well assuming you don’t need to simplify

44/100

0.44

44%

Step-by-step explanation:

Okay so fraction is easy, theres a 100 cubes in total, 44 are shaded in, 44/100 are shaded in which is the area in this scenario.

Decimal is basically moving the place area by a specific amount, in this case theres no whole number since the whole number is 1 or 100/100 and its 44/100 right now so it can’t be a whole number. Decimals go by tenths, hundreths, thousandths, etc. so in this case 44/100 is n the hundreth place since its over a hundred so its 0.44. Or you can move it twice to the right by the times of 0 that appears.

Percent basically means out of 100. So in this case its 44 out of a hundred or 44%

So in this case it’s 44 out of a 100 or 44%

 To know where to put the dots on the graph, use the coordinates you've just been given:

Example: (4,8)

Move to the 4 on the x-axis (the line on the bottom going horizontal)

Then, move up 8 units (up to the 8 on the y-axis)

Place the point at that spot.

A - (1,2)

B - (2,4)

C - (3,6)

D - (4,8)

 Derek decorates 10 cookies in 5 minutes. We know he took 5 minutes to decorate 10 cookies because in the table, the x-axis is told to us that it represents the time it takes. Since the x coordinate is 5 in the point (5,10) and the y coordinate is 10, we can safely say that it took Derek 5 minutes to decorate 10 cookies.
