An office supply store is selling markers in packages of 2 and packages of 5. if the store sold 7 packages containg a total of 23 markers, how many of the packages contained 2 markers?

  4

Step-by-step explanation:

If all packages contained 5 markers, then 35 markers would have been sold. Instead, a number 12 fewer than that was sold.

The sale of a 2-marker package instead of a 5-marker package reduces the marker count by 3 for each 2-marker package. Hence there were 12/3 = 4 packages of 2 markers sold.

___

If you like, you can write an equation for x = the number of 2-marker packages. Then the total number of markers sold was ...

  2x +5(7-x) = 23

  -3x +35 = 23 . . . . simplify

  -3x = -12 . . . . . . . . subtract 35

  x = -12/-3 = 4 .  . . . divide by 3

4 packages contained 2 markers.

i do not know this sorry : (

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
