Xavier is twice as old as Yasmin is. Xavier will 30 years old in six years. What is the total of their ages now?
Let's think: If in six years Xavier will be 30 years old, he is 30 - 6 = 24 years old now. If Xavier is twice as old as Yasmin, Yasmin is 24 / 2 = 12 years old. The total of their ages now is 12 + 24 = 36 years.. The answer is: 36.

Mildred and Candice went to the market. Mildred spent $25 while Candice spent $35. If their mom gave them $100 to spend, how much will be left with them after spending?
Let's think: Mildred and Candice spent $25 + $35 = $60 in total. Therefore, they were left with $100 - $60 = $40 after spending.. The answer is: 40.

Sam bought a dozen boxes, each with 30 highlighter pens inside, for $10 each box. He rearranged five of these boxes into packages of six highlighters each and sold them for $3 per package. He sold the rest of the highlighters separately at the rate of three pens for $2. How much profit did he make in total, in dollars?
Let's think: Sam bought 12 boxes x $10 = $120 worth of highlighters. He bought 12 * 30 = 360 highlighters in total. Sam then took 5 boxes 6 highlighters / box = 30 highlighters. He sold these boxes for 5 * $3 = $15. After selling these 5 boxes there were 360 - 30 = 330 highlighters remaining. These form 330 / 3 = 110 groups of three pens. He sold each of these groups for $2 each, so made 110 * 2 = $220 from them. In total, then, he earned $220 + $15 = $235. Since his original cost was $120, he earned $235 - $120 = $115 in profit.. The answer is: 115.

Toby wants to walk an average of 9,000 steps per day over the next week. On Sunday he walked 9,400 steps. On Monday he walked 9,100 steps. On Tuesday he walked 8,300 steps. On Wednesday he walked 9,200 steps. On Thursday he walked 8,900 steps. How many steps does he need to average on Friday and Saturday to meet his goal?
Let's think:
He needs to walk 63,000 steps in a week because 7 x 9,000 = 63,000. He has 18,100 steps to walk on Friday and Saturday because 63,000 - 9,400 - 9,100 - 8,300 - 9,200 - 8,900 = 18,100. He needs to walk an average of 9,050 on Friday and Saturday because 18,100 / 2 = 9,050.. The answer is: 9050.
