From the given table, the positive sign connote deposit while the negative sign connotes withdrawal.
If the account shows a zero balance after 4 weeks, we will take the sum of all deposits and withdrawals for the first four weeks and equate to zero as shown:
![+120+(-100)+50+p=0](https://tex.z-dn.net/?f=%2B120%2B%28-100%29%2B50%2Bp%3D0)
Open the parenthesis:
![+120-100+50+p=0\\20+50+p=0\\70+p=0](https://tex.z-dn.net/?f=%2B120-100%2B50%2Bp%3D0%5C%5C20%2B50%2Bp%3D0%5C%5C70%2Bp%3D0)
Subtract 70 from both sides
![70+p-70=0-70\\p=-70](https://tex.z-dn.net/?f=70%2Bp-70%3D0-70%5C%5Cp%3D-70)
Hence the value of p if the account shows a zero balance after 4 weeks is -70

Answer:
275 yards of ribbon need to be ordered
Step-by-step explanation:
Figure out how much ribbon, in inches, is needed altogether by multiplying the amounts of ribbon by how many boxes are expected to sell for both box sizes:
Small Boxes:
20 in • 225 boxes = 4500 in of ribbon needed
Large Boxes:
30 in • 180 boxes = 5400 in of ribbon needed
Add it up to see how much you need:
4500 + 5400 = <u>9900 in of ribbon needed in total</u>
<u />
There are 36 inches in 1 yard, so divide 9900 by 36 to see how many yards need to be ordered:
9900 ÷ 3 = 275 yards
(Alternatively, you could divide 9900 by 12 inches in a foot to get 825 feet. Then you would divide 825 by 3 feet in a yard to get 275 yards)

Question #1:
To find the percentage of boy's in the class, divide.
9 / 36 = 0.25
0.25 * 100% = 25% (boys in the class)
We can write this proportion as 9/36 since this is the same as 25%.

Question #2:
We know that the ear buds in both options cost $125.
The earbuds online are on a 20% discount.
The earbuds in store are on a 90$ sale
Lets find the discount for the online pair.
20% = 0.2
125 * 0.2 = 25
125 - 25 = $100 (price after discount)
After solving we can see that the earbuds in store are a better price. So, you will purchase the ear buds in store.

If it is a 10 by 10 then it would be 100. if it was a 5 by 15 it would be 75
