Question: Roger bought a house for $100,000. He was able to pay 20% down, and his parents paid off an additional 30% of the remaining balance. How much money does Roger still owe on his house?
Answer: Step-by-step reasoning process: 100000(.20) = 20000$ down payment. 100000 - 20000 = $80000 remaining. 80000(.30) = 24000. 80000 - 24000 = 56000$.
So the answer is 56000.

Question: Jenna is adding black dots to a bunch of white blouses. Each blouse gets 20 dots, and each dot takes 10 ml of black dye. How many 400-ml bottles of dye does Jenna need to buy to dye 100 blouses?
Answer: Step-by-step reasoning process: First find the amount of dye each blouse takes: 20 dots / blouse * 10 ml / dot = 200 ml / blouse. Then multiply the dye used per blouse by the number of blouses to find the total amount of dye used: 200 ml / blouse * 100 blouses = 20000 ml. Then divide the amount of dye needed by the amount of dye per bottle to find the number of bottles needed: 20000 ml / 400 ml / bottle = 50 bottles.
So the answer is 50.

Question: It is Roger’s turn to provide a snack for the baseball team after the game and he has decided to bring trail mix. The trail mix comes in packs of 6 individual pouches. Roger has 13 members on his baseball team, plus 3 coaches and 2 helpers. How many packs of trail mix does he need to buy?
Answer: Step-by-step reasoning process: Roger will need 13 + 3 + 2 = 18 pouches of trail mix. If you divide the amount of trail mix pouches by the amount in each pack, 18 / 6 = 3 packs of trail mix.
So the answer is 3.

Question: Marnie makes bead bracelets. She bought 5 bags of 50 beads and 2 bags of 100 beads. If 50 beads are used to make one bracelet, how many bracelets will Marnie be able to make out of the beads she bought?
Answer:
Step-by-step reasoning process: Marnie bought 50 x 5 = 250 beads from the 5 bags of 50 beads. She also bought 100 x 2 = 200 beads from the 2 bags of 100 beads. She has a total of 250 + 200 = 450 beads. Hence, she will be able to make 450 / 50 = 9 bracelets.
So the answer is 9.
