Answer:
A and C
Step-by-step explanation:
X is the number of weeks, so it is a possitive number. As the debt reduces while weeks advance, then there should be a substraction between total debt and payments, therefore options C and D are not possible
Debt would start as a negative number in -825, and would reduce up to zero. You know that you he can pay more but not less than 85 per week, so suppouse he pays more than 85, let's say $100, then the debt should be 100-825=-725 that is larger than 85-825=-740. So The option A represent the amount of debt
2 question
After 3 weeks Martin has payed at least: 85*3=255. So debt is not more tha 825-255=570, so scenario A is possible
With the sema logic, after 4 wekks debt is not larger than: 825-4*85=485, so option B is possible
After 5 weeks: debt is not larger than= 825-5*85=400. So scenario C is NOT possible
After 6 weeks debt is not larger than 825-6*85=315, so scenario D is possible
