Answer 1

1. The score changed by 110. Since 30 x 3= 90 you do 200 - 90= 110

2. -78-21=-99

3. $15 35-20 = 15

4. He lost 70 points for going over the time limit and lost and additional 100 points 100-70=30 its a 30 point difference

9. He lost 14 points 4 x 6= 24 - 10=14

10. So he pays $48 for babysitting and the wife gives him $10 so $48 - $10= $38 so im guessing this means how much he has in the wallet so its $38

Answer 2

1. 110

2. -99

3. $35

4. $30

9. 14 points

10. Amount in his wallet reduced by $38

Explanation:

1.

Number of points lost = 30 × 3 = 90

Number of points earned at the end of level 3 = 200

Therefore, the score changed by 200 - 90 = 110

2. - 6(13)-21 = - 78 - 21 = - 99

3. Amount paid by Bella = 7×5 = $35

Amount received by Bella = $20

Therefore, change in amount of money with Bella = 35 - 20 = $15

4. Points lost by Ron playing a video game= 10 ×7 =70

Points lost for going over the time limit = 100

Therefore, total change in his score = 100 - 70 = $30

9. Number of questions in a test = 25

Points lost = 4 x 6= 24

Points earned = 10

Therefore, he lost 24 - 10 = 14 points

10. Amount given to babysitter = $12 × 4 = $48

However his wife gives him $10, so he has to pay just $48 - $10 = $38

Therefore, amount in his wallet reduced by $38
