Answer: D)
Explanation:
Hi, to answer this question we have to analyze the information given:
1750 − 250x = 1000.
So, in this expression $1750 is the amount of money that the Russell family started with, and 250 is the cost of each day on vacation.
Since the cost of each day is multiplied by a variable, the variable "x" is the number of days that the Russell’s have been on vacation.
1000 is the money left to spend.
Option d)
