_____/12 pts                  Date _________________________

1) x- = -                          4)
= -3

2) -2k =                                5) s - =

3) 2h – 3.24 = -1.1                     6) Tickets to an orchestra concert cost
\$25.50 apiece plus a \$2.50 handling
fee for each order. If Jamal spent
\$79, how many tickets did he
purchase?
EXTRA CREDIT: Lucie drank ¾ pint of bottled water. One serving of the
water is 7/8 pint. How much of a serving did Lucie drink?

1) -1/8
2) -1/8
3) 1.07
4) -78
5) 1 13/24
6) 3 tickets
7) 6/7
1) x-       =   -                  4)
+¼          + ¼ Common Denom             = -3

x = -3/8 + 2/8                    reverse PEMDAS to “undo”

x = - 1/8                           multiply both sides by 32

x-18 = -3 * 32

x-18 = -96

x = -78

3) -2k =                                5) s -       =

divide both sides by -2                       +2/3        +2/3

k = ¼ ÷ -2/1                          s= 7/8 + 2/3 find a common denom

k= ¼ *-½                              s= 21/24 + 16/24

k = - 1/8                             s= 37/24        reduce

s = 1 13/24

3) 2h – 3.24 = -1.1                     7) Tickets to an orchestra concert cost
+ 3.24   +3.24                       \$25.50 apiece plus a \$2.50 handling
fee for each order. If Jamal spent
2h = 2.14                                  \$79, how many tickets did he
purchase?
divide both sides by 2
T= number of tickets
h= 1.07
25.50T + 2.5 = 79

subtract 2.5 from both sides
divide by 25.50

T=3; 3 tickets
EXTRA CREDIT: Lucie drank ¾ pint of bottled water. One serving of the
water is 7/8 pint. How much of a serving did Lucie drink?

1 serving = 7/8 of a pint
