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
Answer:
15
Step-by-step explanation:
4 ×15= 60
60×2= 120
166-46=120
Answer:
(1) $11955.38
(2) $12228.62
(3) $12293.527
(4) $12326.6
Step-by-step explanation:
Compound interest is given by
A= P( 1 + r/n)^n*t
A= Final amount
P = initial amount = 6000
r = interest rate = 9% = 0.09
n = number of times interest applied per time period
t = number of time periods elapsed
(1) Compounded annually
n = 1 , t = 8
A = 6000( 1+ 0.09/1) ^1*8
A = 6000( 1.09) ^8 = $11955.38
(2) compounded quarterly
n = 4 , t = 8
A = 6000( 1+ 0.09/4) ^4*8
= 6000( 1.0225)^32 = $12228.62
(3) compounded monthly
n = 12 , t = 8
A = 6000( 1+0.09/12)^12*8 = $12293.527
(4) compounded continuously
A = P* e^rt
r = 0.09 , t = 8
= 6000* e^0.09*8
= 6000* e^0.72 = $12326.6
A. Is correct because unless you want to have 10 dimes in April and 20 dimes in May you would normally just have however many you have if you know what I mean
