4. For the jkl company, the expression to represent the situation is 7($5 - $12 + $3). To find the value of the expression, we can calculate: 7($5 - $12 + $3) = 7(-$4) = -$28. So the net gain or loss for the jkl company is a loss of $28.
5. The expression that shows the net gain or loss for the ghi company is 8($-2 + $9 + $6). To find the value of the expression, we can calculate: 8($-2 + $9 + $6) = 8($13) = $104. So the net gain or loss for the ghi company is a gain of $104.
6. To find the overall gain or loss, we need to sum up the net gains or losses for all the companies. In this case, we have a gain of $5 (for abc company), a loss of $25 (for def company), a gain of $104 (for ghi company), and a loss of $28 (for jkl company). Adding these values, we get $5 + (-$25) + $104 + (-$28) = $56. So the overall gain or loss is a gain of $56.
7. The expression to represent the change in the submarine's position is 4(-45) + 112. To find the value of the expression, we can calculate: 4(-45) + 112 = -180 + 112 = -68. So the change in the submarine's position is a decrease of 68 feet.
8. The expression to represent Giselle's final score is 17(5) + 0(3) + 5(-2) + 8. To find the value of the expression, we can calculate: 17(5) + 0(3) + 5(-2) + 8 = 85 + 0 + (-10) + 8 = 83. So Giselle's final score is 83 points.
9. The expression to represent the change in Hugh's account balance is -20 + (-20) + (-12) + (-20) + (-12) + (-42) + 57 + (-15). To find the value of the expression, we can calculate: -20 + (-20) + (-12) + (-20) + (-12) + (-42) + 57 + (-15) = -158. So the change in Hugh's account balance is a decrease of $158.
To complete the table and answer questions 1-4, we need to calculate the net gain or loss for each situation.
For the abc company, you own 5 shares and the changes in value are as follows:
- Monday: Lost $2
- Tuesday: Gained $5
- Wednesday: Lost $1
To find the net gain or loss, we need to add up the changes in value: (-$2) + $5 + (-$1) = $2.
Since the result is positive ($2), the net gain is $2.
For the def company, you own 2 shares and the changes in value are:
- Monday: Gained $8
- Tuesday: Lost $7
- Wednesday: Lost $10
To find the net gain or loss, we add the changes in value: $8 + (-$7) + (-$10) = -$9.
Since the result is negative (-$9), the net loss is $9.
For the ghi company, you own 8 shares and the changes in value are:
- Monday: Lost $2
- Tuesday: Gained $9
- Wednesday: Gained $6
To find the net gain or loss, we add the changes in value: (-$2) + $9 + $6 = $13.
Since the result is positive ($13), the net gain is $13.
For the jkl company, you own 7 shares and the changes in value are:
- Monday: Gained $5
- Tuesday: Lost $12
- Wednesday: Gained $3
To find the net gain or loss, we add the changes in value: $5 + (-$12) + $3 = -$4.
Since the result is negative (-$4), the net loss is $4.
So the answers to questions 1-4 are:
1. Net gain
2. Net loss
3. Net gain
4. Net loss
Now, moving on to question 5, which asks for an expression representing the net gain or loss for the ghi company.
Since we already established that the net gain for the ghi company is $13, the expression would be: 8 × $13 = $104.
For question 6, to find the overall gain or loss, we need to sum up the net gains/losses for all companies mentioned (abc, def, ghi, jkl).
Net gain/loss for abc: $2 (from question 1)
Net gain/loss for def: -$9 (from question 2)
Net gain/loss for ghi: $13 (from question 3)
Net gain/loss for jkl: -$4 (from question 4)
To find the overall gain or loss, we add up these amounts: $2 + (-$9) + $13 + (-$4) = $2 - $9 + $13 - $4 = $2 - $9 - $4 + $13 = $73.
So the overall gain is $73.
Moving on to question 7, which asks for the change in the submarine's position. The information provided states that the submarine made 4 dives, each time descending 45 feet more, and then rose 112 feet.
To find the change in the submarine's position, we can write the expression: 4 × (-45) + 112.
Calculating that, we get: -180 + 112 = -68.
So the change in the submarine's position is -68 feet.
For question 8, it asks for Giselle's final score on a test. The given information says that she answered 17 questions correctly (5 points each), left 3 blank (0 points each), had 5 wrong answers (-2 points each), and got 8 out of 10 points for extra credit.
To find her final score, we can write the expression: 17 × 5 + 0 × 3 + 5 × -2 + 8.
Calculating that, we get: 85 + 0 + (-10) + 8 = 83.
So Giselle's final score is 83 points.
Lastly, for question 9, it asks for the change in Hugh's account balance. The information provided states that he wrote six checks in different amounts, made a deposit, and was charged a service fee.
The expression to represent the change in his account balance would be: -20 + (-20) + (-12) + (-20) + (-12) + (-42) + 57 + (-15).
Calculating that, we get: -148 + 57 - 15 = -106.
So the change in Hugh's account balance is -$106.
I hope this answers your questions! Let me know if you need any further assistance.
