Seth and Max were selling candy bars for a school fundraiser. Seth sold 6 more candy bars than 3 times the number of candy bars that Max sold. If Max sold 24 candy bars, how many did Seth sell?

Let C be the number of candy bars Seth sold

3*24 +6=C

72+6=C

C=

<<78=78>>78 #### 78 Lyka wants to buy a smartphone worth $160 but she only has $40 at the moment. She plans to save an equal amount of money per week for two months for the remaining amount that she needs. How much should she save per week? Lyka has to save a total of $160 - $40 = $<<160-40=120>>120 for two months. There are 2 x 4 = <<2*4=8>>8 weeks in two months. Hence, Lyka needs to save $120/8 = $<<120/8=15>>15 per week. #### 15 A plane takes off at 6:00 a.m. and flies for 4 hours from New York City to Chicago. The plane stays at the port in Chicago for 1 hour and then departs for Miami. If the aircraft took three times as many hours to fly to Miami than it took to fly from New York to Chicago, calculate the total time to travel from New York to Miami. Before departing for Miami from Chicago, the total time the plane had taken for the journey is 4+1 = <<4+1=5>>5 hours. It took 3*4 = <<3*4=12>>12 hours to fly to Miami The total flying time from New York to Miami is 12+5 = <<12+5=17>>17 hours #### 17 Brody’s calculator can run for 60 hours on a full battery. Brody has used three quarters of its battery up, and he is about to take a two-hour math exam that will require his calculator the whole time. How many hours of battery will Brody’s calculator have left? Brody’s calculator has 60 * 1/4 = 60 / 4 = <<60*1/4=15>>15 hours of battery left. After his 2-hour math exam, Brody’s calculator will have 15 - 2 = <<15-2=13>>13 hours of battery left. #### 13 Lauren sent 65 pieces of mail on Monday, 10 more pieces of mail on Tuesday than on Monday, 5 fewer on Wednesday than on Tuesday, and 15 more pieces of mail on Thursday than on Wednesday. How many pieces of mail did Lauren send? Lauren sent 65 + 10 = <<65+10=75>>75 pieces of mail on Tuesday. He sent 75 - 5 = <<75-5=70>>70 pieces of mail on Wednesday. And sent 70 + 15 = <<70+15=85>>85 pieces of mail on Thursday. Therefore, he sent 65 + 75 + 70 + 85 = <<65+75+70+85=295>>295 pieces of mail. #### 295 Socorro is preparing for a math contest. She needs to train for a total of 5 hours. Each day, she answers problems about multiplication for 10 minutes and then division problems for 20 minutes. How many days will it take for her to complete her training? Socorro trains for a total of 10 + 20 = <<10+20=30>>30 minutes each day. She needs to train for a total of 5 x 60 = <<5*60=300>>300 minutes since an hour has 60 minutes. Therefore, she will complete her training in 300/30 = <<300/30=10>>10 days. #### 10 Mr. and Mrs. Boyden take their 3 children to a leisure park. They buy tickets for the whole family. The cost of an adult ticket is $6 more than the cost of a child ticket. The total cost of the 5 tickets is $77. What is the cost of an adult ticket? Let X be the cost of an adult ticket. So the cost of a child ticket is X-6. The total cost of the 5 tickets is X*2 + 3*(X-6) = 77. X*2 + 3*X - 3*6 = 77. 5*X - 18 = 77. 5*X = 77 + 18 = 95 X = <<19=19>>19 #### 19 Jill has a difficult test to study for. She decides to study one day for 2 hours. The next day she doubles this amount, and the day after that she studies one hour less than the previous day. How many minutes does Jill study over the 3 days? First, we need to determine how many hours Jill studied in total. To find this out, we begin by performing 2*2= <<2*2=4>>4 hours spent on day two, double what she spent on day 1. Next, we perform 4-1= <<4-1=3>>3 hours to determine the amount she studied on the third day. We then add 2+4+3= <<2+4+3=9>>9 hours spent in total across 3 days. Since there are 60 minutes in an hour, she studied 9*60=<<9*60=540>>540 minutes in total. #### 540 Darma can eat 20 peanuts in 15 seconds. At this same rate, how many peanuts could she eat in 6 minutes? There are 60 * 6 = <<60*6=360>>360 seconds in 6 minutes. Then there are 360/15 = <<360/15=24>>24 sets of 15 seconds. So, Darma could eat 24 x 20 = <<24*20=480>>480 peanuts. #### 480 Bruce's aunt gave him $71 to spend on clothes at the mall. He bought 5 shirts that cost $5 each and a pair of pants that cost $26. How much money does Bruce have left to buy more clothes? Bruce spent 5 * $5 on shirts = $<<5*5=25>>25. Including the pants, Bruce spent $25 + $26 = $<<25+26=51>>51. Since he began with $71, he has $71 - $51 spent = $<<71-51=20>>20 remaining. #### 20
