The marked price of the projector is $50,000.
<h3>What is the marked price?</h3>
The price of the projector after the discount can be represented with:
(100 - 10%)x - 90%x = 0.90x
Where x is the marked price
The price of the projector after the VAT is : (1.13) x 0.90x = 1.02x
Difference in price = 1.02x - 0.90x = 5850
0.12x = 5850
x = 5850 / 0.12
x = $50,000

3) you’re subtracting 9 each time.. the 3 missing numbers are -39,-48,-57
With inverse functions you just swap 'x' and 'y' and solve for 'y'.

Swap 'x' and 'y':

Add 7 to both sides:

Take the square root of both sides:
