Danivan Drugstore has 4500 bottles of hand sanitizer gel in inventory at the beginning of the week. On Monday 2445 bottles were sold, on Tuesday 900 bottles were sold, and 50 bottles each day for the rest of the week were sold (from Wednesday until Sunday). On Saturday, the supplier delivers an order for 650 bottles. How many bottles of sanitizer gel does the Drugstore have at the end of the week? Give the rationale and then the answer.
Let's think step by step. The number of bottles sold on Monday and Tuesday is 2445 + 900 = 3345 bottles. Each day of the rest of the week, 50 bottles were sold, that is 5 * 50 = 250 bottles sold. Now the total of bottles sold in a week is 3345 + 250 = 3595 bottles. The drugstore has in stock 4500 – 3595 = 905 bottles. Finally the drugstore has 905 + 650 the supplier brought = 1555 bottles at the end of the week.. The answer is: 1555.

Cynthia harvested 67 potatoes from her garden. After washing them, she cut 13 of them into wedges. She then halved the remaining potatoes and made french fries with one half, and potato chips with the other half. If one potato can be cut into 8 wedges or make 20 potato chips, how many more potato chips than wedges did Cynthia make? Give the rationale and then the answer.
Let's think step by step. Cynthia was left with 67 - 13 = 54 potatoes after making wedges. She used 54 / 2 = 27 potatoes to make potato chips. Cynthia made 13 x 8 = 104 wedges. She made 27 x 20 = 540 potato chips. Cynthia made 540 - 104 = 436 more potato chips than wedges.. The answer is: 436.

Mia is buying Christmas gifts for her family. She has spent $30 on each of her 3 siblings, and the rest of her spending was for her parents. If Mia spent a total of $150 on Christmas gifts and each of her parents received gifts of equal value, how much money, in dollars, did she spend on each parent’s gift? Give the rationale and then the answer.
Let's think step by step. Mia spent a total of $30 per siblings * 3 siblings = $90 on her siblings. She therefore spent $150 total spending - $90 spending on her siblings = $60 on her parents. As each parent received an equal amount, each parent’s gift cost $60 total spending on parents / 2 = $30.. The answer is: 30.
