Hello,
I'm a student in distance education programm. I had a math exam and got 1 mistake. I tried to analyze my mistake but didn't understand. English is my second language and that is the reason why I ask this question.
Could you please point me which part of word problem I have misinterpreted?
Johnson earns $200 a week plus a 15% commission on all sales
over $1,000. If Mr.
Johnson's sales for one week are $2,500, what is his gross pay for
that week?
A. $350
B. $425
C. $525
D. $575
15%=0.15
$2500*0.15=$375 ... this is his commission money
$200 ... this is his weekly pay
$575 ... this is his gross pay
So the answer SHOULD be D.$575, but it's not... it's B.
Well it's bit hard concept for me yes I know it looks stupid but I'll try to explain how I understood it.
I've seen many times in shops specials deals like ''buy something over $50 and get 10% off'' and always it's off of whole $50 and never like this:
(total-$50) - 10%
I hope that my humble English made any sense
I don't want to get on your nerves...
When advertisment states ''5% discount on all sales over $100'', does it means that if I shop for $101 I'll get only $0.05?
I'm confused because I've used discounts and specials deals many times and I didn't have even one situation when precents where calculated only from remainder.
It's always
$100> pay whole sum
$100< get discount for whole sum because it's OVER $100
This is reason why I want to make sure that i really understand
