Question

nick has $18.25 on his transit card now. he wants to add money to the card so that the final amount is $30. how much money should he add? describe the situation with an equation.

Explanation:

Step1: Define variables and equation

Let $x$ = money Nick adds. The initial amount plus added money equals final amount:
$18.25 + x = 30$

Step2: Solve for x

Subtract 18.25 from both sides:
$x = 30 - 18.25$

Step3: Calculate the value

Compute the difference:
$x = 11.75$

Answer:

The equation is $18.25 + x = 30$, where $x$ is the money Nick adds. Nick should add $\$11.75$.
