Question 7: The pattern is that each price is getting higher by $5.15 per hour, so multiply 5.15 by 2 to get the amount it'd be higher by 2 hours. The answer would be 10.30. Add $23.95 and $10.30 and you get $34.25 as your final answer
Question 8: The pattern in this question is that each price is getting lowered by $2.75 as more dogs get added. So, since it only shows the price per dog for 4 dogs, you have to multiply $2.75 by 4, and you get $11. Since thats the amount of money she's removing as she walks 4 more dogs, you subtract $11 from $31.75 ($31.75 - $11) and get your answer of $20.75.
