You have to divide 300 with 15, the answer to that is: 300/15=20. However, if she starts saving this week (counting as a first), she will have enough money in 19 weeks after the first week, she needs 20 weeks to save the money.
Answer:
The formula for an exponential decay problem is: y = x (1 - r)^x
Where x = initial amount, r = rate of decay and x = # time periods
So, x = $258, r = 8% = .08 and x = 11 years
y = 258 (1 - 0.08)^11 = 258 (0.92)^11 = 258 * 0.3996 = $103.10

Answer:
Area = 3x^5+3x^4-3x^3-3x^2
Step-by-step explanation:
Area equals length times width
x(x+1) * 3x(x^2-1)
(x^2+x) * (3x^3-3x)
3x^2(x+1)(x^2-1)
3x^5+3x^4-3x^3-3x^2
