OA.A.3; 4.NBT.B.5 UNIT 2 2. Mary bought 6 packages of jewels. Each package had 36 jewels. She used 54 jewels make a bracelet. Sh
e used 102 to make a necklace. Which equation can be used to determine j, how many jewels she has left? a. (54 x 6) - 36 - 102 = j b. (36 x 6) - 54 - 102 = j c. 6(36 -54 - 102)= j d. (36 x 6) + 54 - 102 = j
Because we know that she bought 6 bags of 36 jewels. So the first part we would need to solve would be the total number of jewel she purchased. Which would be . Then, you must find the total number of jewels that she used. Which would be . This means that the equaltion would be the total number of jewels-the total numnber of jewels used. Aka:
