By conservation of momentum,
(900 kg) (15.0 m/s) i + (750 kg) (20.0 m/s) j = (900 kg + 750 kg) v
where v is the velocity vector of the combined cars. Solve for v :
(13,500 i + 15,000 j) kg•m/s = (1650 kg) v
v ≈ (8.18 i + 9.09 j) m/s
Then the direction of v relative to East is θ such that
tan(θ) ≈ 9.09/8.18 ⇒ θ ≈ 48.0°
so the wreckages would move at approximately 48.0° north of east.

Explanation:
Introductory blurbs often contain valuable information. They'll always provide basic information about the passage, like title and author name, but they can also contain important definitions or pieces of useful background knowledge.
Tax= sales price x tax percent
Tax= $40 x 6.5%
Convert % decimal to decimal: 6.5% by 100
Tax= 40 x 0.065
Tax= $2.60
Answer: sales tax is $2.60
Hope this helps!
