#1) Write TWO equations that represents this numberline: 

30 - 10 

30 + (-10) 


100

#5) What is a unit rate? Provide an example 

the rate of one of something. 


I can buy 100 peppermints with $10. 

Unit Rate#1: 

Unit Rate#2: 

100

#9


15%

560-476 = 84     1. Find the difference 

84/560=0.15      2. Divide by Original 

.15*100= 15%   3. Convert to percent 

  

100

#13. What is simple interest?

The percent of the original amount

#17) Values for variables x, y and z are graphed on the number line shown. 

Is x - z: 

A. less than zero 

B. equal to zero 

C. greater than zero

A. less than zero

x = -3 and z = 4 

-3 - 4 

-3 + (-4) = -7

#2) Which situation results in a final value of zero?

  1. A deposit of $278 followed by a withdrawal of $278

  2. The temperature after a decrease of 2℉ from a temperature of -2℉

  3. The distance between 24 ft below sea level and 24 ft above sea level.

  4. The height of an airplane after taking off from ground level and rising 500 feet.

1. A deposit of $278  followed by a withdrawal of $278

Deposit: + change       

Withdrawal: - change                   

$278 - $278 = $0

#14


D. $2875.00


2500*15%= $375              1. Find simple interest 

2500 + 375 = $2875.00      2. Find total amount 

200

#18) Values for variables x, y and z are graphed on the number line shown. 

Is z - y

A. less than zero 

B. equal to zero 

C. greater than zero

C. greater than zero

z= 4 and y = -1 

4 - (-1) 

4 + 1

                                                                          #3) Evaluate the expression:

        -10 - (-1) + 5 - 2

  1. -18

  2. -12

  3. -8

  4. -6



D

 -10 - (-1) + 5 - 2

-10 + 1 + 5 + (-2)   Rewrite into addition 

-12 + 6                   Combine (pos) and (negs)

#11


B. $173.25

1. Apply coupon   175 -10 = $165 

2. Apply sale tax   165*1.05 = $173.25

*DAILY DOUBLE*

#15

A. $309

simple interest: 4% per year

4% / 12 = 1/3% per month 

1/3%*9 = 3% in 9 months 

300*3%= $9 earned 

$300 + $9 = $309

#19) Two points are plotted on the open number line below and drawn to scale. Which of the following expressions has the largest value? Explain your thinking.

  1. A - B

  2. B - A

  3. B + A 

2

A = -1   and B = 3 

-1 - 3                 3 - (-1)                   3 + (-1) 

-1 + -3               3 + 1                         2

-4                         4

**Daily Double**

#12



B. $667.80


1. Apply discount     900*.70= 630 

2. Apply sales tax    630*1.06 = 667.8

400

#16


B. $19,890


17,000*4.25*4= 2890

17,000 + 2890 = $19,890
