A family bought 1 box of pizza that is cut into 16 slices. Only three-fourths of the pizza was eaten by the family. How many slices of pizza were left?

The family ate 16 x 3/4 =

<<16*3/4=12>>12 slices. So, there were 16 - 12 = <<16-12=4>>4 slices of pizza left. #### 4 Ms. Estrella is an entrepreneur with a startup company having 10 employees. The company makes a revenue of $400000 a month, paying 10% in taxes, 5% of the remaining amount on marketing and ads, 20% of the remaining amount on operational costs, and 15% of the remaining amount on employee wages. Assuming each employee receives the same wage, calculate the amount of money each employee is paid monthly. The company pays a total of 10/100*$400000 = $<<10/100*400000=40000>>40000 on taxes After taxes, the company revenue is $400000-$40000 = $<<400000-40000=360000>>360,000 The costs of marketing and ads campaign are 5/100*$360000 = $<<5/100*360000=18000>>18000 After deducting the costs of marketing and adds campaign, the company remains with = $342,000 in revenue Operational costs for the company are 20/100*$342000 = $<<20/100*342000=68400>>68400 After taking out the operational costs, the company remains with $342000-$68400 = $273600 The company also pays employee wages of 15/100*$273600 =$<<15/100*273600=41040>>41040 If the total number of employees is 10, each employee is paid a salary of $41040/10 = $4104 per month #### 4104 The largest frog can grow to weigh 10 times as much as the smallest frog. The largest frog weighs 120 pounds. How much more does the largest frog weigh than the smallest frog? To find the weight of the smallest frog, 120 pounds / 10 = <<120/10=12>>12 pounds for the smallest frog. The difference is 120 - 12 = <<120-12=108>>108 pounds. #### 108 Emily spent X dollars on Friday, twice that amount on Saturday, and then three times X on Sunday. Over the three days, she spent $120. What is the value of X, in dollars? She spent X dollars on Friday. She spent 2X dollars on Saturday. She spent 3X dollars on Sunday. X+2X+3X=120 6X=120 X=<<20=20>>20 #### 20 Kathleen receives a weekly allowance for completing all of her chores. During middle school, her allowance was $2 more than $8 but during her senior year, her allowance was $5 more than twice her middle school allowance. What is the percentage increase in Kathleen's weekly allowance? Kathleen's allowance in middle school was $8 + $2 = $<<8+2=10>>10. Twice her middle school allowance is $10 x 2 = $<<10*2=20>>20. So, Kathleen's senior year allowance is $20 + $5 = $<<20+5=25>>25. Her allowance increased by $25 - $10 = $<<25-10=15>>15. Kathleen's percent increase in her weekly allowance is $15/$10 x 100% = <<15/10*100=150>>150%. #### 150 Tony puts $1,000 in a savings account for 1 year. It earns 20% interest. He then takes out half the money to buy a new TV. The next year, the remaining money earns 15% interest. How much is now in the account? After one year he earns $200 in interest because 1,000 x .2 = <<1000*.2=200>>200 After one year it has $1,200 in the account because 1,000 + 200 = <<1000+200=1200>>1,200 He takes out $600 because 1,200 / 2 = <<1200/2=600>>600 After this it has $600 in it because 1,200 - 600 = <<1200-600=600>>600 She earns $90 in interest because 600 x .15 = <<600*.15=90>>90 The account now has $690 because 600 + 90 = <<600+90=690>>690 #### 690 Madison makes 30 paper boats and sets them afloat. 20% are eaten by fish and Madison shoots two of the others with flaming arrows. How many boats are left? First find the number of boats eaten by fish: 30 boats * 20% = <<30*20*.01=6>>6 boats Then subtract the two groups of boats that were destroyed from the original number to find the number left: 30 boats - 6 boats - 2 boats = <<30-6-2=22>>22 boats #### 22 Charles can earn $15 per hour when he housesits and $22 per hour when he walks a dog. If he housesits for 10 hours and walks 3 dogs, how many dollars will Charles earn? Housesitting = 15 * 10 = <<15*10=150>>150 Dog walking = 22 * 3 = <<22*3=66>>66 Total earned is 150 + 66 = $<<150+66=216>>216 #### 216 Every Monday to Friday morning, Alice walks 10 miles through a large grass field to get to school. To avoid the hot afternoon sun on her way home, she walks 12 miles through a forest. When she gets home on Friday, how many miles will she have walked that week? On Monday the total number of miles Alice walks to and from school is 10 + 12 = <<10+12=22>>22 miles. For the other 4 days, from Tuesday to Friday, she walks an additional 4 * 22 = <<4*22=88>>88 miles The total number of miles she will have walked by Friday 22 + 88 = <<22+88=110>>110 miles #### 110 Val cuts a single watermelon into 40 slices, and each slice has 20 black seeds and 20 white seeds. What is the total number of seeds in a watermelon? 40 slices per watermelon and each slice having 20 black seeds means each watermelon has 20*40=<<20*40=800>>800 black seeds. 40 slices per watermelon and each slice having 20 white seeds means each watermelon has 20*40=<<20*40=800>>800 white seeds. In total, each watermelon has 800+800=<<800+800=1600>>1600 seeds. What is the total number of seeds in a watermelon? #### 1,600
