Answer:

(20, -2)

Step-by-step explanation:

Given the coordinate vectors p=(4,3) and q=(-2,7),

4p - 2q = 4(4, 3)- 2(-2, 7)

4p - 2q = (16, 12) - (-4, 14)

4p - 2q = (16+4, 12-14)

4p - 2q =(20, -2)

hence the required vector is (20, -2)

You find yourself with 17 guilders( a gold coin) but you are planning on taking a trip to a country where the local currency is

3241004551 [841]

We are given

The current exchange rate is 2 guilders for every 3 florins

so,

2 guilders = 3 florins

now, we can find for 1 guilders

so, we get

$1guilders=\frac{3}{2} florins$

now, we can multiply both sides by 17

$17\times 1guilders=17\times \frac{3}{2} florins$

now, we can simplify it

$17guilders=25.5florins$

so, option-A........Answer
