Answer:
Step-by-step explanation:
first lets seperate them
7x3=21
3x7=21 21/2= 10.5
10.5x21=220.5
keeping in mind that
x = percent rate for the 17000 investment.
y = percent rate for the 11000 investment.
so the amount for the 17000 interest will just be (x/100) * 17000, or namely 170x.
and the amount of interest earned for the 11000 is (y/100) * 11000, or just 110y.
now, regardless of what "x" and "y" are, we know that the interest from the 17000 is higher by 308 bucks, therefore 170x = 110y + 308.
we also know that the rate of <u>x</u> is higher as well than <u>y</u> by 0.4%, so then x = y + 0.4.
The discount is 15%, multiply the price y 15%:
5000 x 0.15 = 750
The discount is 750
