The negative sign shows that they still owed $5000 to the creditors which shows a loss of money between June and December.
Step-by-step explanation:
Amount owed at the end of June = $3765
Amount owed at the end of December = $8765
As Hightop Roofing owed creditors the amount, therefore, we will consider the amount as negative, therefore,
Amount in June = -3765
Amount in December = -8765
To see the difference, we will subtract the amount owed in June from the amount owed in December.

Answer:
Ernest gets 194 monthly allowance
Step-by-step explanation:
* Lets revise the rule of the average
- Average = The sum ÷ the total number
- Assume that the allowances money of Ernest, Jack, David and Mike
are E, J, D, M respectively
∵ The average allowance money of Ernest jack David and mike is
123 per month per person
∴ 123 = (E + J + D + M) ÷ 4
- Multiply both sides by 4
∴ E + J + D + M = 492 ⇒ (1)
∵ The average allowance of Ernest jack and David is 159 per month
per person
∴ 159 = (E + J + D) ÷ 3
- Multiply both sides by 3
∴ E + J + D = 477 ⇒ (2)
- Subtract equation(2) from equation (1) to find M
∴ M = 15
* <em>Mike's monthly allowance is 15</em>
∵ David's monthly allowance is 2 less than mikes
∴ D = M - 2
∵ M = 15
∴ D = 15 - 2 = 13
∴ <em>David's monthly allowance is 13</em>
∵ Mikes monthly allowance is 1/18 of jacks
∴ M = × J
∴ 15 = × J
- Multiply both sides by 18
∴ J = 270
* <em>Jack's monthly allowance is 270</em>
- Substitute the values of D , J in equation (2) to find E
∵ D = 13 and J = 270
∵ E + J + D = 477
∴ E + 270 + 13 = 477
∴ E + 283 = 477
- Subtract 283 from both sides
∴ E = 194
* <em>Ernest's monthly allowance is 194</em>
*<em> Ernest gets 194 monthly allowance</em>
