35% off means 35% of the original price, $625.00, will be subtracted from that original price. 35% is equal to 0.35.
$625.00 - $625.00(0.35) = $625.00 - $218.75 = $406.25
Cosθ = adjacent / hypotenuse

I hope I helped you^_^
Answer is the second one .
hope it helps
F(x) = 3x
F(7) = 21
g(x) = -x + 1
g(7) = -7 + 1 = -6
(F x g)(7) = (21) (-6) = -126
