Answer:
She will make $232.1 in all over 4 weeks.
Step-by-step explanation:
Lucy's lemonade stand has increasing profit each week = 10%
Her profit for the initial week = $50.00
here the profit earned in every week will make a geometrical sequence.
In this sequence first term (a) = $50
and the common ratio (r) =
= 1.1
sum of n terms of this sequence = ![\frac{a(r^n-1)}{r-1}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%28r%5En-1%29%7D%7Br-1%7D)
by substituting the values,
![=\frac{50[(1.1)^4-1]}{1.1-1}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B50%5B%281.1%29%5E4-1%5D%7D%7B1.1-1%7D)
![=\frac{50(1.4641-1)}{0.1}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B50%281.4641-1%29%7D%7B0.1%7D)
![=\frac{50(0.4641)}{0.1}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B50%280.4641%29%7D%7B0.1%7D)
![=\frac{23.205}{0.1}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B23.205%7D%7B0.1%7D)
= 232.05 ≈ $232.1
She will make $232.1 in all over 4 weeks.
Answer:

Answer:
Jill bought 16 books and Sam bought 9 books
Step-by-step explanation:
Let the number of books that Jill bought be j.
Let the number of books that Sam bought be s.
Jill bought 7 more books than Sam:
j = 7 + s
They bought 25 books altogether:
j + s = 25
Put j = 7 + s into the second equation:
7 + s + s = 25
7 + 2s = 25
2s = 25 - 7 = 18
s = 18/2 = 9 books
Therefore:
j = 7 + s = 7 + 9
s = 16 books
Jill bought 16 books and Sam bought 9 books.
