$122.57 • 4 + $555.28 = $1,045.56
$136.71 • 4 + $585.34 = $1,132.18
$1,132.18 - $1,045.56 = $86.62
Answer:
So,

And,

But, given g(a) = 7
So, from 2nd and 3rd step,
3a-1=7
3a=6
Therefore, a = 2
6x + 8y = 24
x intercept is the value when y =0 & y intercept is the value when x=0
for y=0 ==> 6x+0 =24 ==> x=4 for x=0==> 0+8y =24 ==> y=3
(4,0) & (0,3) (ANSWER d)
It would be 6x5 squared-5x4+8
150-20+8=138
