Answer:
Let x and y be the two numbers. Then
yx=57 and x−y=20
Cross multiplying the proportion
5x=7y or y=75x
So, x−y=20
x−75x=20⇒77x−5x=72x=20
⇒x=2140=70
y=75x=75×70=50
So smaller number is 50.
Check :yx=5070=57 and 70−50=20

If there is supposed to be a decimal
Answer:
$7420
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year,
then, solving our equation
I = 7000 × 0.02 × 3 = 420
I = $ 420.00
The simple interest accumulated
on a principal of $ 7,000.00
at a rate of 2% per year
for 3 years is $ 420.00.
