Step-by-step explanation:
you have $4000 to invest and you invest x dollars at 10% and the remainder at 8℅.
a) an expression in x that represent the amount invested at 8% is
4000 - x
b) The The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal
R represents interest rate
T represents time in years
I = interest after t years
From the information given
P = $x
R = 10%
Assuming the investment is for 1 year, then interest,
I = (x × 10 × 1)/100
I = $0.1x
c) P = 4000 - x
R = 8℅
I = [(4000 - x) × 8 × 1)]/100
I = (32000 - 8x)/100
I = 320 - 0.08x
d) the total interest earned is
I = 0.1x + 320 - 0.08x
I = 0.02x + 320
