Answer:
$2.63
Step-by-step explanation:
3 x $0.79 = 2.37
5.00 - 2.37 = $2.63
Step-by-step explanation:
log <base a> b = x
means
a^x = b
So
3^2 = x^2+7x+21
x^2 + 7x + 21 - 9 = 0
x^2 + 7x + 12 = 0
(x+3)(x+4)
x = -3 or -4
So what you want to do is multiply 245 by 1.65 (because it’s +65%) and by doing that you get $404.25 :)
