PLEASE HELP!!!!

Answer: she will make $232.05 in 4 weeks.

Step-by-step explanation:

Since her profit is increasing by 10% each week, then the rate at which it is increasing is in geometric progression. The common ratio, r would be 110/100 = 1.1

We would apply the formula for determining the sum of n terms of a geometric progression which is expressed as

Sn = a(r^n - 1)/(r - 1)

Where

a represents the first term of the sequence.

r represents the common ratio.

n represents the number of terms(number of weeks)

From the information given,

a = 50

r = 1.1

n = 4 weeks

Therefore,

S4 = 50(1.1^4 - 1)/(1.1 - 1)

S4 = 50(1.1^4 - 1)/0.1

S4 = $232.05

Answer:

$x=2\frac{1}{12}$

Step-by-step explanation:

1. The first step is to get 14.8 on the other side. It is a positive number which means that you have to subtract 14.8 on both sides:

$32.3=14.8+8.4x$

$17.5 = 8.4x$

2. The second step is to get x by itself. Right now it is being multiplied by x so to get it by itself you have to do the opposite of multiplication which is division, so you will divide 8.4 by both sides:

$\frac{17.5}{8.4} = \frac{8.4x}{8.4}$

$x=2\frac{1}{12}$
