D
Step-by-step explanation:
(b) What will the total repayment amount be (including interest)? X
Answer:
a) Simple interest paid = $360
b) Total repayment amount = $6360
Step-by-step explanation:
It is given that:
Principal, P = $6000
Rate of interest, R = 2%
Time, T = 3 years
(a) Total interest paid:
Formula for Simple Interest is given as:
Putting the values of P, R and T to find out Simple Interest:
(b) Total repayment amount:
We know that formula for total amount is given as:
Amount = Principal + Simple Interest
Amount = 6000 + 360 = $6360
So, total repayment amount = $6360
So, the answers are:
a) Simple interest paid = $360
b) Total repayment amount = $6360
and
Answer:
number x
y = 3x +3
sum = x + y
19 = x + 3x + 3
19 = 4x + 3
19- 3 = 4x
16 = 4x
16/4 = x
x = 4
Answer:
Solution: x=5, y=4
Step-by-step explanation:
System of Equations
We need to solve:
- 5x + 9y = 11
x - 3y = - 7
There are several ways to solve a system of linear equations. We'll take advantage of the second equation since it has the x with coefficient 1 and solve it for x:
x = - 7 + 3y
Now replace it into the first equation:
- 5(- 7 + 3y) + 9y = 11
Operate:
35 - 15y + 9y = 11
Simplify:
35 - 6y = 11
Rearrange:
- 6y = 11 - 35 = -24
Solve:
y = -24 / -6
y = 4
Finally, since
x = - 7 + 3y
x = - 7 + 3*4
x = - 7 + 12
x = 5
Solution: x=5, y=4
Answer:
constant
