[Answer]Amoli = 42 * 3 = 126 miles. Anayet = 61 * 2 = 122. Together = 126 + 122 = 248 miles. 369 - 248 = 121 miles. They still have 121 miles to travel. The answer is 121.
Q: Susie babysits every day for 3 hours a day at the rate of $10 per hour. She spent 3/10 of the money she earned from last week to buy a make-up set. She then spent 2/5 of her money on her skincare products. How much is left from her earnings last week, in dollars?
A: Susie earned $10 x 3 = $30 per day. Last week, she earned a total of $30 x 7 = $210. She spent $210 x 3 / 10 = $63 on make - up. While she spent $210 x 2 / 5 = $84 on her skincare products. Thus, she spent a total of $63 + $84 = $147 from her earnings. Therefore, Susie is left with $210 - $147 = $63 from her earnings last week. The answer is 63.
Question: Tonya has opened a lemonade stand selling lemonade in small, medium, and large cups at $1, $2 and $3 respectively. At the close of business she ended up making $50. As she went back through her inventory she noticed that she sold $11 worth of small lemonades and $24 worth of medium lemonades. How many cups of large lemonade did Tonya sell?
Answer: 1. Tonya sold $11 worth of small lemonades and $24 worth of medium lemonades which makes $11 + $24 = $35 for small and medium lemonades. 2. Tonya made a total of $50. If she made $35 selling the two smaller sizes and she sold three sizes in all then $50 - $35 = $15 worth of large lemonades. 3. The large lemonades sold for $3 each and Tonya sold $15 worth of large lemonades which means she sold $15 / $3 = 5 large cups of lemonade. The answer is 5.

Q: A sixty bulb watt uses 60 watts of power each day. If Allyn has 40 such bulbs in his house and pays an electricity bill of twenty cents per power watt used, calculate Allyn's total monthly expenses on electricity in June.
A: If each bulb uses 60 watts each day, the 40 bulbs that Allyn has uses 60 * 40 = 2400 watts of power each day. In June, with 30 days, the bulbs will use 30 * 2400 = 72000 watts of power. If Allyn is charged an electricity bill of twenty cents per power watt used, in June she will pay 72000 * $0.20 = $14400. The answer is 14400.
Question: A gift shop sells bracelets at $15 each, a gold heart necklace at $10, and a personalized coffee mug at $20. Raine buys three bracelets, two gold heart necklaces, and one coffee mug for her friends. How much change does Raine get back if she gives a one hundred dollar bill?
Answer:
Three bracelets cost 3 x $15 = $45. Two gold necklaces cost 2 x $10 = $20. Thus, the total amount is $45 + $20 + $20 = $85. Therefore, Raine gets a change of $100 - $85 = $15. The answer is 15.
