0.84(20)=$16.80
700/100=7
7(1.02)=$7.14
$7.14+16.80=$23.94 in total
The answer is x = 5. Hope that helps, God bless!
equation of line in slope intercept form is
y = mx + c
where m is slope.
putting point (0,5) in equation
5 = m × 0 + c
c = 5
now equation is
y = mx +c
y = (-1/2)x + 5
answer is option D
