P/L=4/7 and P=L-12 so
(L-12)/L=4/7 multiply both sides by 7
(7L-84)/L=4 multiply both sides by L
7L-84=4L subtract 4L from both sides
3L-84=0 add 84 to both sides
3L=84 divide both sides by 3
L=28, and since P=L-12
P=16
So they had 28+16 = £44 in total.
Answer:
The correct answer is D.
Step-by-step explanation:
D. Yes, because the Shermans paid a higher percentage of their income in sales tax than the Westins did.
The Westins made $86,000 (high income)
The Shermans made $33,000 (low income)
But both paid the same sales tax rate of $14,000.
Regressive tax is applied uniformly and this causes lower-income people to pay a larger share of their income than rich people. It is not a fair way though it seems to be. Most regressive taxes are not income taxes.
