511 divided by 7 is the unit rate. So a is how you get it but d is the answer
B. is the answer to your question!! Hope this helps!! :D
We know that pupils are students
Students = S
boys = B
Teachers = T
So....
S = 8T
Boys = 3G
T = B - 70
Since there is 8x students than teachers, I did Boys = 6x and girls = 2x
I'm going to use this next: S = 8T
8x = 8(B -70)
8x = 8(6x - 70)
8x = 4x - 560
x = 14
We know there is 8x students, so there are 112 students and we know that there is 1/8 of teachers, so there are 14 teachers.
Answer = 126.
So a tax was mentioned, but not the tax percent, which is needed to find out that tax for a 1700 dollar vase.
Divide 54 by 600, and you get 0.09 or 9%.
1700 * 9% = 153
So your tax is $153.
Hope this helps. :)
