For this case what you should know is that the vector ab will be given by:
ab = b-a
We have then:
ab = (3, 5) - (- 2, 4)
ab = ((3 - (- 2)), (5-4))
ab = (5, 1)
Equivalently the vector is:
ab = 5i + 1j
Answer:
ab = 5i + 1j
Answer: 18.
if aliyah gave 2 to her 4 children, thats 4x2 which equals 8, plus the 10 she took to get 18.

$12 x .30= $3.60 mark up so new price was $15.60.
$15.60 x .25= $3.90 discount, so the new price with discount would be $11.70
