Laci and Leon are saving money to go to an amusement park. Laci has [tex]$1[/tex] more than 4 times Leon's amount. Which equation represents this situation?

A. [tex]4x + 1 = 76[/tex]

B. [tex]x + 4x - 1 = 76[/tex]

C. [tex]4x - 1 = 76[/tex]

D. [tex]x + 4x + 1 = 76[/tex]

Answer :

To solve the problem, we need to determine which equation correctly represents the situation described.

The problem states: "Laci has [tex]$1 more than 4 times," which we need to interpret as Laci having an amount that is $[/tex]1 more than 4 times some variable, let's call it [tex]\( x \)[/tex]. This situation is mathematically represented as:

[tex]\[ 4x + 1 = 76 \][/tex]

Now, let's solve this equation step by step:

1. Start with the equation:
[tex]\[ 4x + 1 = 76 \][/tex]

2. Subtract 1 from both sides to begin isolating [tex]\( x \)[/tex]:
[tex]\[ 4x = 76 - 1 \][/tex]

3. Simplify:
[tex]\[ 4x = 75 \][/tex]

4. Divide both sides by 4 to solve for [tex]\( x \)[/tex]:
[tex]\[ x = \frac{75}{4} \][/tex]

5. Simplify the result:
[tex]\[ x = 18.75 \][/tex]

Therefore, the correct interpretation of the situation is represented by the equation [tex]\( 4x + 1 = 76 \)[/tex], and the solution for [tex]\( x \)[/tex] is 18.75.
