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.
Well, you know that the area of the rectangle is 12 square feet. And you know one of the numbers multiplied to get 12 is 5, so divide 12 by 5. You would get 2.4 as the other number needed.
In this case, 5 feet is the width and 2.4 feet is the length.
-7.9 and 17/8 should be the answers!
