Decide which unit rate is greatest and explain why using complete sentences.
• 12 apples for $4
• 21 apples for $8
• 35 apples for $14
. 45 apples for $16

Greatest unit rate/cost is $0.40/apple.

Step-by-step explanation:

Find the unit rate in both cases.

12 apples for $4 => $4/12 = $0.33/apple

21 apples for $8 => $8/21 = $0.38/apple

35 for $14 =>  $0.40/apple

45 for $16 => $0.36/apple

Having done this, we quickly see that the highest price is $0.40/apple (the 3rd case).

Step-by-step explanation:

1) 12 apples for $4

Cost of 1 apple = 4/12 = $ 0.33

2)  21 apples for $8

Cost of 1 apple = 8/21 = $ 0.38

3)35 apples for $14

Cost of 1 apple = 14/35 = $ 0.4

4) 45 apples for $16

Cost of 1 apple = 16/45 = $ 0.36

unit rate is greatest  for 35 apples for $14

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.
