Answer:

Charles completed the quiz problems at the slowest rate

Step-by-step explanation:

we know that

To find out the unit rate divide the number of quiz problems by the time employed

1) Maya completed 15 quiz problems in 10 minutes

so

\frac{15}{10}=1.5\ quiz\ problems\ per\ minute

2) Andrew completed 12 quiz problems in 8 minutes

so

\frac{12}{8}=1.5\ quiz\ problems\ per\ minute

3) Charles completed 16 quiz problems in 16 minutes

so

\frac{16}{16}=1\ quiz\ problem\ per\ minute

Compare the unit rates

1 < 1.5

therefore

Charles completed the quiz problems at the slowest rate

QUESTION EIGHT: 2690

QUESTION NINE: 120

QUESTION ELEVEN: 12.5

QUESTION FOURTEEN: 24

<u>Step-by-step explanation:</u>

8.

may 3rd -> july 15th = 73 days

500*0.06 = 30

30 = how much he makes in one day (so he has 530 after 1 day)

30*73 = 2190

500 + 2190 = 2690

9.

210/7 = 30

1% for 3 years = 30

1% for 1 year = 10

100% for 1 year = 1000

2000*0.06 = 120

11.

54,000*0.08 = 4320

54,000/4320 = 12.5

14.

5000*6.26% = 312.5

7500/312.5 = 24
