Tony is spending money at a constant rate. Suppose he initially has $1000, and after 4 months, he has $760, Which of these expresses the rate at which Tony's amount of money is changing?

Step-by-step explanation:

Step one:

The initial amount that Tony has= $1000

final amount =$760

amount spent= 1000-760= $240

time taken is 4 months

Step two:

Required:

the rate of spending

we know that rate= quantity/time

rate= 240/4

rate= $60 per month

Hence Tony's amount is changing at $60 monthly
