Answer:
the answer is c
Step-by-step explanation:
Becuase he is given 100 dollars and he uses 20 dollars a day, so you put x with 20 to calculate how many days that he can spend $20 on
Day 1: money spent = 20
Day 2: total money spent = 20+20 = 2*20
So, for x days, total spent money should be 20*x = 20x
At an instant, say, after x days.
=> saving = total amount - spent
=> money left = 100 - 20x
=> y = 100 - 2x
=> y = - 2x + 100
