0.73 is your answerrrrrrrr
The greatest common factor is 7 .
Ava's sister paid a 4.5% annual interest rate
Her sister paid $54 more than she borrowed, divide that by 3 (years till she paid)
54/3 = 18
That's $18 for every year she'd had the $400 loan out, divide it by 4 to get the percentage
18/4 = 4.5/100 = 4.5%
3(x-4)(2x-3)=0
(x-4)(2x-3)=0
x=4
x=3/2
