Answer ; k=2h−2x+y
Step-by-step explanation:
Suppose he makes the payment with two equal annual instalments, the present value of the amount he is owing is $1,543 , the interest rate is 23.76% = 0.2376.
The amount of payment he makes in two of the periodic payments is given by:

Therefore, in 2 years, the amount he has paid for the tools is 2(1,056.20) =
2,112.40
The function given is:
h(x) = 3x-19
we want to find the value of x that makes this function equal to 71. To do so, we will substitute h(x) with 71 and solve for x as follows:
h(x) = 3x - 19
71 = 3x - 19
3x = 71+19
3x = 90
x = 90/3 = 30
Answer: The no. is 8
Step-by-step explanation:
Let the no. be x
6x - 1 = 47
6x = 48
x = 8
Answer:
Amount of interest after 7 years = $12335.06
Step-by-step explanation:
First total number of quarters in 7yrs is calculated
a year has four quarters, hence 7yrs will have = 4 x 7 = 28 quarters
Using the compound interest expression
Amount after 7 yrs = P(1+r%)²⁸
A = 3000 (1+0.06)²⁸ = $15335.06
Hence amount of interest after 7 years = 15335.06 - 3000 = 12335.06
