. Julie borrows $25,000 at an effective annual interest rate of 12%. She has the following options for repayment: (i) Annual amortization method, with payments made at year-end for 10 years
(ii) Paying annual interest at year-end and building up a sinking fund (earning an effective annual interest rate of 7%), by making level annual payments at year-end, to pay off the loan at the end of 10 years Determine the absolute value of the difference between the total annual outlay under option 1 and the total annual outlay under option 2.

step-by-step explanation:

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
