Callie has 18 seeds. She planted 10 of the seeds. Callie have _______ number of seeds now

It takes 2 moves to count on from 6 to 8. So, 8 – 6 = 2

Peter has 16 grapes.
Peter has 10 grapes left
So, the number of grapes he ate is (16-10)=6

Callie has 19 seeds.
She planted 4 of the seeds
The number of seeds she is left with are:19-4=15 seeds

It takes 4 moves to count on from 1 to 5. So, 5 – 1 = 4.

Peter has 20 grapes.
Peter has 3 grapes left.
The number of grapes Peter ate is:(20-3)=17 grapes

It takes 7 move to count on from 3 to 10. So, 10 – 3 = 7

It takes 1 move to count on from 2 to 3. So, 3 – 2 = 1

Callie has 18 seeds
She planted 4 of the seeds
The number of seeds she has left is:18-4=14 seeds

Peter has 19 grapes
Peter has 9 grapes left
The number of grapes he ate is 19-9=10 grapes

It takes 3 moves to count on from 2 to 5. So, 5 – 2 = 3

Callie has 14 seeds.
She planted 11 of the seeds
The number of seeds she has now=14-11=3 seeds

Peter has 14 grapes
Peter has 7 grapes left
The number of grapes he is left with=14-7=7 grapes

It takes 2 moves to count on from 6 to 8. So, 8 – 6 = 2

Step by step solution:
Given,
Callie in total has 16 seeds.
Number of seeds Callie planted = 7
Thus, remaining number of seeds = 16 - 7 = 9
Therefore, Callie has 9 seeds now.
Hence, option (b) is the correct option.

Step by step solution:
Clearly in the shown picture,
it takes 1 gap to go from 9 to 10.
Hence, 10 - 9 = 1
Thus, option(b) 1 is the correct option.
