Let's solve each of these mental math word problems step by step and explain the reasoning.

1. William needs to sell 25 Husky Cards for a fundraiser by Friday. So far, he has sold 9 cards. How many tickets does he still need to sell?
Solution:
Total needed = 25
Already sold = 9
Remaining = 25 - 9 =
16
✔ Answer: A) t = 16

2. 4c = 12
We need to solve for
c.
Divide both sides by 4:
$$
c = \frac{12}{4} = 3
$$
✔ Answer: C) 3

3. Robyn had some video games then bought 4 more. Now she has a total of 10 games.
Let
v be the number of games she originally had.
Then:
$$
v + 4 = 10
$$
Subtract 4 from both sides:
$$
v = 10 - 4 = 6
$$
✔ Answer: A) v = 6
---
4. y / 6 = 4
Multiply both sides by 6:
$$
y = 4 \times 6 = 24
$$
✔ Answer: A) y = 24

5. Jane is 3 years older than Sam. If Jane is 12, how old is Sam?
Let Sam’s age =
s
Jane = s + 3
But Jane is 12:
$$
s + 3 = 12
\Rightarrow s = 12 - 3 = 9
$$
✔ Answer: B) j = 9
(Note: The variable is labeled "j", but in context it's Sam’s age — likely a typo in labeling; we interpret "j" as Sam’s age here.)
Wait — actually, the question says: *"If Jane is 12, how old is Sam?"* and gives options like
j = 9, which suggests that
j represents Sam’s age. That’s confusing notation, but based on logic:
Jane = 12
Sam = 12 - 3 = 9 → So
Sam is 9
So if
j = 9, and j is Sam’s age, then yes.
✔ Answer: B) j = 9

6. r + 20 = 27
Subtract 20 from both sides:
$$
r = 27 - 20 = 7
$$
✔ Answer: B) r = 7

7. Which choice models this situation?
The image cuts off after question 7, so we don’t see the full question or choices. Without additional information (like what the situation is), we can't answer this one.
✘ Incomplete question – cannot solve without more details.

✔ Final Answers:
1.
A) t = 16
2.
C) 3
3.
A) v = 6
4.
A) y = 24
5.
B) j = 9
6.
B) r = 7
7.
