Carla can babysit for 5 hours and tutor for 7 hours or babysit for 8 hours and tutor for 5.5 hours
<h3>How to graph the inequality?</h3>Let x represents hours babysitting and y represents hours tutoring
So, we have:
Earnings = Rate of babysitting * x + Rate of tutoring* y
This gives
Earnings = 5x + 10y
He wants to earn at least $95.
This means that:
5x + 10y ≥ 95
See attachment for the graph of the inequality
From the attached graph, two possible solutions are: (5, 7) and (8, 5.5)
This means that Carla can babysit for 5 hours and tutor for 7 hours or babysit for 8 hours and tutor for 5.5 hours

Answer:
25%
Step-by-step explanation:
As the given situation the parameters are below:-
Cost of each box = 3 pounds
Amount of cereal in each box = 160 g
now,
160 g of cereal = 100%
and
25% of 1 box of cereal = 25% of 160 g which is
As per the question, it is mention that Jane need her idea to give the equal value of amount as Tim's idea, provided
160 g of cereal costs 3 pounds
and
1 g of cereal will cost
=
40 g of cereal will cost
So, the percentage of the pound is of 3 pounds is 3 ÷ 4 ÷ 3 × 100
= 25%
Therefore as the situation, Jane need to decline the amount by 25% for the same amount as Tim's idea.
