Let's find the rates at which Melinda and Marcus are saving money and compare them.
Based on the table, we can see that Melinda originally had $75. Then she got $135 in 5 weeks. So the rate of saving money is (135–75)/5 = $12 per week.
This rate is unchanged for the next weeks. As we can see, she got $195 in the next 5 weeks. So she saved $60 more those 5 weeks, or the rate is $60/5 = $12 per week again.
So Melinda saved $12 per week.
As for Marcus, the equation tells us that the rate of saving money is $14 which is the coefficient in front of x.
Hence, t<span>he rate at which Melinda is adding to her savings each week is 2$
less than the rate at which Marcus is adding to his savings each week.</span>
Answer:
Odds are 3 to 7
Step-by-step explanation:
The odds are defined as the probability that the event will occur divided by the probability that the event will not occur.
Let's find:
Probability of blue marble = 3/10 [ 3 blue and 10 in total]
Probabilty of NOT blue marble = 7/10 [7 marbles are red and green (not blue) and 10 in total]
Hence,
Odds of drawing a blue marble =
The odds are 3 to 7
