<u>Second Discount</u>
20% off means we paid 80%. We know we paid $328 of some price.
I can now cross-multiply by multiplying numerator and denominator from each ratio.
I now solve for y by dividing by 80.
The price after the first discount was $410.
<u>First Discount</u>
We will repeat the steps above with $410. 18% off means we paid 82%.
I can now cross-multiply by multiplying numerator and denominator from each ratio.
I now solve for y by dividing by 82.
The original price was $500.
Answer:
The right solution is:
(a) $1,940
(b) $2,813
Step-by-step explanation:
Given:
Invoice amount
= $8,400
Discount 1
= 33.33%
Discount 2
= 12.5%
So,
The net payable amount will be:
=
=
= ($)
Now,
(a)
Amount paid will be:
=
= ($)
Balance still to be paid will be:
=
= ($)
(b)
Amount paid will be:
=
=
= ($)
Balance still to be paid will be:
= ($)
Thus the above solution is the appropriate one.
