Answer:

Joshua can spend up to 3.21 on a card.

To solve, first subtract 21.79 from both sides to get:

Answer:
150,000*3^t for 6 hour increments (t=1 is 6 hours t=2 is 12)
150,000*3^(t/6) for hourly increments, each t is 1 hour.
Step-by-step explanation:
Well super simply you could do 150,000*3^t where t is measured in 6 hour intervals. so t=1 is 6 hours, and to get 1 hour you would need to do t=1/6
If you want t to be an increase of every hour you would just need to adjust, like I showed before 1/6 gets one hour so 150,000*3^(t/6) would be the model where every t increases by 1 hour.
