Below is Sofie and Kirk's shopping list from their most recent trip to the mall:
Back at home, Sofie and Kirk decided to split the expenses this way: Sofie will pay for all the groceries. Kirk will pay for all the garage tools. To find out how much money they each need to pay, Sofie and Kirk first will solve for the answers to these problems:
(1) What is the total amount they spent for the whole shopping list?
(2) What is the total amount of grocery expenses in the shopping list?
(3) What is the total amount of hardware expenses in the shopping list?
(4) At the mall, Sofie and Kirk split up. Sofie gave Kirk $60 for his trip to the hardware store. If Sofie only has to pay for the groceries, how much money should Kirk give back to her from the $60?
(5) If Kirk gave Sofie $20 for her trip to the grocery store, how much money should Sofie give back to him from the $20?
Were you able to solve for the answers? Did the tips you learned about adding and subtracting decimals help you to solve for the answers?
