Danielle has a cd at crossland bank. she invest $22,350 for four years at 4.55% interest. compounded monthly. what is her ending balance? how much interest did she make?

Her ending balance is $26,703.837 and her interest is $4,353.837

Step-by-step explanation:

First year,

p =22350 R = 4.55 T = 1

Interest = PRT/100

= 22350 × 4.55 × 1 / 100

=$1016.925

P = $22350 + $1016.925 = $23366.925

For the 2nd year,

I = $23366.925 × 4.55 × 1 / 100

=$1063.195

p= $23366.925 + $1063.195 = $24,430.12

For the 3rd year,

I = $24,430.12 × 4.55 × 1 / 100

= $1111.57

p = $24,430.12 + $1111.57 = $25,541.68

For the 4th year;

I = $25541.68 × 4.55 × 1 / 100

= $1,162.147

P = $ 25541.69 + $1,162.147 = $26,703.837

Therefore th ending balance is $26,703.837

Her compound interest is , $26,703.837 - $22350 =$4,353.837

We know that the number of workers doubles every week.

This implies that the number of workers of the previous week is exactly half of the current one's.

So, it took 11 weeks for the factory to be at half capacity.
