70$ with 12% discount
If 12% is 25 then 100% is (25/12) x 100 ie 208.33
$48, a $12 Discount. 10% of 60 is 6...so 20% is $12.
If it's 12% per year, compounded annually, then it is: 100 * (1 + 0.12)-2 = 79.72
The amount saved is $9.35 and the sale price is $68.56
A savings of 6.54 and a discount price of 47.96

percent for 12/19 = 63.16%% rate:= 12/19 * 100%= 0.6316 * 100%= 63.16%
% rate = 12/104 * 100% = 11.54%
percent of 12 over 40 = 30%% rate:= 12/40 * 100%= 0.30 * 100%= 30%
12 over 30 as a percent = 40%% rate:= 12/30 * 100%= 0.40 * 100%= 40%
To find the monthly rate of interest that yields an annual effective rate of 12 percent, you can use the formula for the effective annual rate: ( (1 + r)^n - 1 ), where ( r ) is the monthly interest rate and ( n ) is the number of compounding periods in a year (12 for monthly). Setting up the equation: ( (1 + r)^{12} = 1.12 ). Solving for ( r ) gives ( r = (1.12)^{1/12} - 1 ), which is approximately 0.009488 or 0.9488%. Therefore, the monthly interest rate is about 0.9488%.
