The number of bottles Erica capped = 6 bottles
The number of bottles Erica broken = 9 bottles
<u>step-by-step explanation</u>:
<u>step 1 :</u>
Let 'x' be the number of bottles broken
Then, the number of bottles capped = Total - broken = 15 - x
<u>step 2 :</u>
For bottles capped successfully = 4 cents
For bottles broken = -2 cents
<u>step 3 :</u>
The total money Erica earned for 15 bottles is 4(15 - x) - 2x = 6
60 - 4x -2x = 6
60 - 6x = 6
54 = 6x
x = 54/6 = 9
∴ bottles broken
, x = 9
<u>step 4 :</u>
bottle caped
, 15-x = 15 - 9
bottle caped = 6 bottles
Thus, Erika broke 9 bottles and caped 6 bottles.

Answer shown and explanation above! Hope this helps!
Answer:
Ball Bearing Volume = (4 / 3) * PI * radius ^3
Volume = (4 / 3) * 3.14159265 * (.35)^3
Volume = (4 / 3) * 3.14159265 * 0.042875
Volume = 0.17959438 cc
1 cc of steel = 7.8 g
Volume of 1 kg of steel = 1,000 cc / 7.8 g per cc
1 kg = 128.205 cc
Number of ball bearings we can make = 128.205 / 0.17959438
Equals 713.86
