Answer:

$21.79 + c \leq 25$

Joshua can spend up to 3.21 on a card.

Explanation:

$21.79 + c \leq 25$ is the correct equation because Joshua is spending 21.79 on flowers, a certain amount on the card, and the maximum he can spend is 25. That is why you use the less than or equal to sign.

To solve, first subtract 21.79 from both sides to get:
$c \leq 3.21$ . This means that Joshua can spend up to 3.21 on a card.

Hope it helps!
