Mrs. Thomas' class has a goal of selling 250 boxes
of cookie dough in three months. The class sold 145
boxes in the first month and 76 boxes in the second
month. Exactly how many more boxes of cookie
dough does the class need to sell reach its goal?
a. 231
b. 39
c. 221
d. 29

D

Step-by-step explanation:

3 months =250 boxes

1st month =145 boxes sold

2nd month =76 boxes sold

Thus 250-(145+76)

=29

D. 29

Step-by-step explanation:

If the class sold 145 boxes of cookie dough in the first month and 76 boxes in the second month, we can add these together and total, they have sold 221 boxes of cookie dough. You then subtract 221 from 250 (250 - 221) and you wind up with 29 boxes of cookie dough, which is how many more boxes they need to sell.

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

x = 17

step-by-step explanation:

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17
