Problem 1:

> Sean got *m* marks for his math test. Emma got 15 more marks than Sean. Emma’s score is 94.

Step-by-step solution:

- Let Sean’s score = m
- Emma’s score = Sean’s score + 15 → m + 15
- We’re told Emma’s score is 94 → So:

> m + 15 = 94

Now, solve for m:

Subtract 15 from both sides:

> m = 94 - 15
> m = 79

✔ Answer: Sean got 79 marks.

Problem 2:

> There are 6 books on the desk and *b* books on the shelf. There are 37 books in total.

Step-by-step solution:

- Books on desk = 6
- Books on shelf = b
- Total books = 37

So, the equation is:

> 6 + b = 37

Solve for b:

Subtract 6 from both sides:

> b = 37 - 6
> b = 31

✔ Answer: There are 31 books on the shelf.

Problem 3:

> The admission for a water park for an adult is 9 dollars. The admission for a child is *x* dollars, which is 4 dollars cheaper than the adult admission.

Step-by-step solution:

- Adult admission = $9
- Child admission = x
- Child admission is $4 cheaper than adult → So:

> x = 9 - 4

Simplify:

> x = 5

✔ Answer: Child admission is $5.

Final Answers:

1. Sean’s score: 79 → Equation: `m + 15 = 94`
2. Books on shelf: 31 → Equation: `6 + b = 37`
3. Child admission: $5 → Equation: `x = 9 - 4`

These are simple one-step equations that model real-world situations using variables — exactly what the worksheet asks for! 📚✏️
