tax on video game : 8% of 39.99 = 0.08(39.99) = 3.199 rounds to 3.20
tax on book : 8% of 12.99 = .08(12.99) = 1.039 rounds to 1.04
3.20 - 1.04 = 2.16 <== tax on video game is 2.16 more then the book
her weekly paycheck was 6500....including the 1000 salary.....so she made (6500 - 1000) = 5500 on commission sales.
so what percent of 45,000 is 5500 ?
percent formula : is/of = %/100
is = 5500
of = 45,000
percent = x
now we sub
5500/45,000 = x/100
cross multiply
45,000x = 550000
x = 550000/45000
x = 12.22 % rounded = 12% <== her commission rate
