Answer:
$900
Step-by-step explanation:
If the $810 is the price after 10% discount that means
$810 is 90% of the original price
So we divide 810 / 90% or 810 / 0.9
to get $900 as final price
Jim goes to the shop and sees that the T-shirts are only $5.75 each and so wishes to buy 3 of them.
Expressed as a fraction $5.75 = $5 3/4
How much does he have to pay?

Answer:
$40
Step-by-step explanation:
x is the original price of the gift
(10% of x) is the value of the discount
(10% of x) = 10/100 . x = 0.1 x
0.1 x is the value of the discount
x - (10% of x) is what was paid, after the discount
x - 0.1 x = 0.9 x
0.9 x is what was paid
4 children paid $9/each
4 times $9 = $36
$36 is the total amount that was paid by the children
$36 = 0.9 x
$36 / 0.9 = x
x = $36 / 0.9 = 360 / 9
x = 40
