Answer:
12 weeks
Step-by-step explanation:
set up a proportion of ounces/weeks = ounces/weeks
12/8 = 18/w
12w = 144
w = 12
Rst you have to find the price of everything together
2 magazines for 9.95 each and a book for 14.95
9.95 + 9.95 + 14.95 = 34.85
Next you convert the percent to a decimal
6% = 0.06
Now you put a one in the ones place
1.06
Multiply this by the cost of everything
34.85 * 1.06 = 36.94
The answer is $36.94
Hope this helps!

Answer:
(16 x^8 - x^3 + 6)/(2 x^3)
Step-by-step explanation:
Simplify the following:
(64 x^8 - 4 x^3 + 24)/(8 x^3)
Factor 4 out of 64 x^8 - 4 x^3 + 24:
(4 (16 x^8 - x^3 + 6))/(8 x^3)
4/8 = 4/(4×2) = 1/2:
Answer: (16 x^8 - x^3 + 6)/(2 x^3)
1 - 8
2 - 16
3 - 32
x - +200
Each lemonade has a profit of $1, so the number of cups of lemonade he sells is the same as the amount of dollars he has. You just need to add each previous day's total to the next day's, doubling the amount of cups from the previous day's for each new day.
4 - (32 x 2 = ) 64
8 + 16 + 32 + 64 = 120. We need at least $80 dollars more, so we continue.
5 - (64 x 2 = ) 128
120 + 128 = $248.00 That's more than enough, so Tom will have enough money for his bike after the fifth day of selling lemonade.
