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 for unknown

Let $x$ = money Nick adds.

Step2: Set up the equation

Current amount + added amount = final amount
$\$18.25 + x = \$30$

Step3: Solve for $x$

Subtract $\$18.25$ from both sides:
$x = \$30 - \$18.25$
$x = \$11.75$

Answer:

The equation describing the situation is $\boldsymbol{18.25 + x = 30}$, and Nick should add $\boldsymbol{\$11.75}$.
