ja, yo is correct, just expand that formula with your calculator
each one is 5% bigger than pevious
each one=previous+previous*5%
each one=previous*1+previous*0.05
each one=previous*(1+0.05)
each one is 1.05 times of previous
so after n years, if today year size is P then
A=final size
so ya, after 18 years, n=18 so you get
A=2067.29 microliters
The answer would be 35 99/100 because you cannot simplify 99/100
The answer is $41.12
(Work is below)
First add the total of the vase and shipping-
Vase: $34.99
Shipping: $ 3.00
+__________
$37.99
Then calculate sales tax by multiplying $37.99 x 0.0825 -
Above Total: $37.99
Sales Tax Rate: $ 0.0825
x__________
$ 3.1341
You round down because ^ less than five (five or above you would round up)
Sales Tax: $3.13
Then you add the sales tax to the above total
Vase: $37.99
Shipping: $ 3.13
+__________
$41.12
down 3 unit mean -3 outside root
right 2 unit mean -2 inside root,
so the answer is
D = 5.5p + 25
D: dollars
P: people attending
