Answer:
$15.75
Step-by-step explanation:
first, figure out the value of the tax. that would be 0.30 because there are 6 cds, and each has a tax of 0.05. next, subtract the tax from the total. that would be 94.50. this gives us the price of the cds alone. lastly, divide the toal by 6. 94.50/6=15.75.
L=5w
96 =2(5w+w)
96=2(6w)
w is 8
So l=5w
The formula for this is A= a + b/2 x h.
This year
2:7
18:?
well 2*9=18
so 7*9=63
18/63
(18+63=total 81 students)
Last year
1/8

9/72
9 less students this year
$420+$144=$564
then you divide $564 by 6 which is...
$94 is how much each person payed
