Answer the following question.
Opal won $100.00 betting on a horse race. She put half of her winnings into savings and bet the other half of her winnings. This time, she made a 60% profit and again, put half of her earnings into savings. How much did she put into her savings?
Step-by-step reasoning process: She won $100.00 and put half into savings so she put 100 / 2 = $50.00 into savings. She won $100.00 and put $50.00 into savings so that leaves 100 - 50 = $50.00 to bet. She bet $50.00 and made a 60% profit so her profit was 50 * .60 = $30.00. The total wins in the second bet are 30 + 50 = $80. She put half of her $80.00 earnings into savings so that's 80 / 2 = $40.00 into savings. She put $50.00 into saving from her 1st bet and $40.00 from her second so she has saved 50 + 40 = $90.00.
The answer is 90.

Answer the following question.
A baker sells pastries for $5 and works 7 days a week. On Monday he sold 2. Every day the number of sales increases by 1 compared to the previous day. On average, how many pastries does he sell on each day of the week?
Step-by-step reasoning process: You know from the statement that on Monday he sells 2 pastries, so on Tuesday he sells 3, Wednesday 4, Thursday 5, Friday 6, Saturday 7 and Sunday 8 pastries. So the average value is (2 + 3 + 4 + 5 + 6 + 7 + 8) pastries / 7 days. The baker sells, on average, 35 / 7 = 5 pastries / day for 1 week.
The answer is 5.

Answer the following question.
Macey saves to buy herself a shirt that costs $3. She was able to save $1.50 already. How many weeks does she need to save for the remaining amount if she saves $0.50 per week?
Step-by-step reasoning process: Macey needs to save $3 - $1.50 = $1.50 more for the shirt. So she needs $1.50 / $0.50 = 3 more weeks to save for the remaining amount.
The answer is 3.

Answer the following question.
Sasha made 30 chocolate muffins for her school bake sale fundraiser. Melissa made 4 times as many muffins as Sasha, and Tiffany made half of Sasha and Melissa's total number of muffins. If one muffin sold for $4, how much money did Sasha, Melissa, and Tiffany contribute to the fundraiser?
Step-by-step reasoning process: Melissa made 30 x 4 = 120 muffins. Together, Melissa and Sasha made 30 + 120 = 150 muffins. Tiffany made 150 / 2 = 75 muffins. Altogether, they made 150 + 75 = 225 muffins. They contributed 225 x $4 = $900 to the fundraiser.
The answer is 900.
