John buys a heating pad for $30. He uses it 3 times a week for 2 weeks. How much does he spend on each use?
He uses it 3*2=
<<3*2=6>>6 times So he pays 30/6=$<<30/6=5>>5 #### 5 A plant supplier was able to sell 20 pieces of orchids for $50 each and 15 pieces potted Chinese money plant for $25. The money he earned was then used to pay his two workers $40 each and to buy new pots worth $150. How much money was left from the plant supplier's earnings? The plant supplier earned $50 x 20 = $<<50*20=1000>>1000 for the orchids. He earned $25 x 15 = $<<25*15=375>>375 for the potted Chinese money plants. So, his total earnings was $1000 + $375 = $<<1000+375=1375>>1375. Then he paid $40 x 2 = $<<40*2=80>>80 to his workers. He used a total of $80 + $150 = $<<80+150=230>>230 for the worker's pay and new pots. Hence, he was left with $1375 - $230 = $<<1145=1145>>1145 from his earnings. #### 1145 Carmen needs $7 more to have twice the amount of money that Jethro has. Meanwhile, Patricia has $60, which is 3 times as much as Jethro. What is the sum of all their money? Jethro has 60/3 = $<<60/3=20>>20. Twice of what Jethro has is $20 x 2 = $40 Carmen has $40 - 7 = $<<40-7=33>>33 The sum of all their money is $60 + $20 + $33 = $<<60+20+33=113>>113 #### 113 Cheryl is signing up for a golf tournament that costs 20% more than her monthly cell phone expenses to enter the tournament. If Cheryl spends $400 more on her monthly cell phone expenses than on the electricity bill, which costs $800, calculate the total amount she pays upon signing up for the golf tournament. If the electricity bill costs $800, and Cheryl spends $400 more on her monthly cell phone expenses than on the electricity bill, she pays $800+$400 = $<<800+400=1200>>1200 on cell phone expenses. Since the cost to enter the tournament is 20% more than Cheryl's monthly cell phone expenses, to enter the tournament, Cheryl has to pay 20/100*1200 = $<<20/100*1200=240>>240 more than her monthly cell phone expenses. The total cost of joining the golf tournament is $1200+$240 = $<<1200+240=1440>>1440 #### 1440 Kamil wants to renovate his kitchen at home. For this purpose, he hired two professionals who work for him 6 hours a day for 7 days. What does it cost Kamil to hire these professionals if one of them is paid $15 per hour of work? Two professionals work together 6 * 2 = <<6*2=12>>12 hours per day. They work for 7 days, so in total it means 7 * 12 = <<7*12=84>>84 hours. The cost of hiring these persons is 84 * 15 = $<<84*15=1260>>1260. #### 1260 4 friends went to buy from a clothes shop. Every item was 50% off. All four friends decided to buy a t-shirt. The original price of the t-shirt was 20 dollars. How much money did they spend in total? After the 50% discount, the t-shirt cost 20 * 0.5 = $<<20*0.5=10>>10. So in all, the 4 friends spent 4 * $10 = $<<4*10=40>>40. #### 40 When Jayson is 10 his dad is four times his age and his mom is 2 years younger than his dad. How old was Jayson's mom when he was born? When Jayson is 10 his dad is 10 x 4 = <<10*4=40>>40 years old. His mom is 40 - 2 = <<40-2=38>>38 years old. When Jayson is born, his mom is 38 - 10 = <<38-10=28>>28 years old. #### 28 Rajesh walked 10 kilometers less than 4 times the distance that Hiro walked. Together they walked 25 kilometers. How many kilometers did Rajesh walk? Let H = distance Hiro walked 4H - 10 = distance Rajesh walked H + 4H - 10 = 25 5H - 10 = 25 5H = 35 Hiro walked 7 km so Rajesh walked 4(7) - 10 = <<7*4-10=18>>18 km Rajesh walked <<18=18>>18 kilometers. #### 18 Lana aims to sell 20 muffins at the bake sale. She sells 12 muffins in the morning. She sells another 4 in the afternoon. How many more muffins does Lana need to sell to hit her goal?
