Answer:
y = -5x + 50
Step-by-step explanation:
We'll write the equation in y = mx + b form, where b is the original amount of money (50), and m is the amount of money he spends he each day(5). Since he's spending 5 dollars, that means that 5 dollars is being lost everyday, so m will be -5:
y = -5x + 50
