Grade 3 word problems worksheet focusing on writing equations with variables.

Problem Analysis:

The image contains three word problems that require writing equations with variables. Let's solve each problem step by step.

---

Problem 1:

Statement: Sean got \( m \) marks for his math test. Emma got 15 more marks than Sean. Emma’s score is 94.

#### Solution:
1. Let Sean's score be \( m \).
2. Emma's score is given as 15 more than Sean's score. Therefore, Emma's score can be expressed as:
\[
m + 15
\]
3. We are also told that Emma's score is 94. So, we can write the equation:
\[
m + 15 = 94
\]

#### Final Equation:
\[
\boxed{m + 15 = 94}
\]

Problem 2:

Statement: There are 6 books on the desk and \( b \) books on the shelf. There are 37 books in total.

#### Solution:
1. The number of books on the desk is given as 6.
2. The number of books on the shelf is given as \( b \).
3. The total number of books is the sum of the books on the desk and the books on the shelf. This is given as 37. So, we can write the equation:
\[
6 + b = 37
\]

#### Final Equation:
\[
\boxed{6 + b = 37}
\]

Problem 3:

Statement: 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.

#### Solution:
1. The admission for an adult is given as 9 dollars.
2. The admission for a child is \( x \) dollars, and it is stated that this is 4 dollars cheaper than the adult admission. Therefore, we can express the child's admission as:
\[
x = 9 - 4
\]
3. Simplifying the right-hand side:
\[
x = 5
\]
However, since the problem asks for an equation, we keep it in the form:
\[
x = 9 - 4
\]

#### Final Equation:
\[
\boxed{x = 9 - 4}
\]

---

Summary of Solutions:

1. \( \boxed{m + 15 = 94} \)
2. \( \boxed{6 + b = 37} \)
3. \( \boxed{x = 9 - 4} \)

These equations represent the relationships described in the word problems. Each equation can be solved further if needed, but the task was to write the equations with variables.
