Answer:

21.79 + c \leq 25

Joshua can spend up to 3.21 on a card.

Step-by-step 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!

Write a positive or negative integer an increase of $15
slamgirl [31]

Answer:

  +15

Step-by-step explanation:

An increase is generally regarded as being positive. If units are dollars, an increase of $15 can be represented by the integer +15.

__

<em>Additional comment</em>

If units are dimes, then the number would be +150. So, you see, <em>the units are important </em>to know.

It also depends on <em>what is increasing</em> and what is being represented by the integer. If it is an increase in debt, then the change in net worth might be -15.
