nancy started the year with $425 in the bank and is saving $25 a week. Seamus started the year with $875 and is spending $15 a w
Goryan [66]

They will have same amount in 45 weeks.

Step-by-step explanation:

Given,

Starting amount of Nancy = $425

Per week saving = $25

Let,

x represent the number of weeks.

N(x) = 25x+425

Starting amount of Seamus = $875

Per week saving = $15

S(x) = 15x+875

For same amount;

N(x) = S(x)

25x+425=15x=875\\25x-15x=875-425\\10x=450

Dividing both sides by 10

\frac{10x}{10}=\frac{450}{10}\\x=45

They will have same amount in 45 weeks.

vodomira [7]

Answer:

A: Since disjoint, P(up AND up AND up) = P(up) P(up) P(up) = .653= .27

A: Disjoint, so previous years have no effect on this year. 1-.65 = .35

A: Same direction; two different probabilities. P(up AND up) = .652 = .42. P(down AND down) = .352= .12. .42 + .12 = .55

trapecia [35]

Answer:

= <em>1</em><em>4</em>

Step-by-step explanation:

So my way of doing it is to simply put 20% in decimal so

20= 0.20

Then multiply that by 70

0.20× 70 = 14%

There are probably other ways to do it but I find this way easier
