Answer:
![21.79 + c \leq 25](https://tex.z-dn.net/?f=21.79%20%2B%20c%20%5Cleq%2025)
Joshua can spend up to 3.21 on a card.
Step-by-step explanation:
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:
. This means that Joshua can spend up to 3.21 on a card.
Hope it helps!

Step-by-step explanation:
<span>The function which has a constant halving time is in the following form
</span>
![A(t) = A_{0} ( \frac{1}{2} )^ \frac{t}{h}](https://tex.z-dn.net/?f=A%28t%29%20%3D%20A_%7B0%7D%20%28%20%5Cfrac%7B1%7D%7B2%7D%20%29%5E%20%5Cfrac%7Bt%7D%7Bh%7D%20)
Where: A₀ is the <span>initial amount
h is the half life time or the halving time.
</span><span> t is the time
</span> A(t) <span>the amount<span> that remains at time t
</span></span>
The previous function represents an Exponential decay<span> function.
</span>
so, The correct answer is option B. <span>
Exponential decay</span>
