TV VAT

A dealer sells a TV for 750 euros. Upon selling it, he must pay 20% VAT to the state. How many euros in VAT will he pay for the sale of one TV?

Final Answer:

d =  125 Eur

Step-by-step explanation:


x+d = 750
d = 20/100x

x+d = 750
d = 20/100·x

d+x = 750
100d-20x = 0

Pivot: Row 1 ↔ Row 2
100d-20x = 0
d+x = 750

Row 2 - 1/100 · Row 1 → Row 2
100d-20x = 0
1.2x = 750


x = 750/1.2 = 625
d = 0+20x/100 = 0+20 · 625/100 = 125

d = 125
x = 625
