Sansa is a famous artist, she can draw a portrait and sell it according to its size. She sells an 8-inch portrait for $5, and a 16-inch portrait for twice the price of the 8-inch portrait. If she sells three 8-inch portraits and five 16-inch portraits per day, how many does she earns every 3 days?

Sansa earns $5 x 3 = $

<<5*3=15>>15 every day by selling three 8-inch portraits. The price of the 16-inch portrait is $5 x 2 = $<<5*2=10>>10 each. So, she earns $10 x 5 = $<<10*5=50>>50 every day by selling five 16-inch portraits. Her total earnings is $50 + $15 = $<<50+15=65>>65 every day. Therefore, the total amount she earns after 3 days is $65 x 3 = $<<65*3=195>>195. #### 195 Archibald eats 1 apple a day for two weeks. Over the next three weeks, he eats the same number of apples as the total of the first two weeks. Over the next two weeks, he eats 3 apples a day. Over these 7 weeks, how many apples does he average a week? He ate 14 apples the first two weeks because 14 x 1 = 14 He ate 14 apples in the next three weeks because 14 = <<14=14>>14 He ate 42 apples in the final two weeks because 14 x 3 = <<14*3=42>>42 He ate 70 apples in total. He averaged 10 apples a week because 70 / 7 = <<70/7=10>>10 #### 10 Susie has $200 in her piggy bank. If she puts 20% more money into her piggy bank, how much money she will have? If Susie puts 20% more money into her piggy bank, she'll have 20/100*200 = $<<20/100*200=40>>40 more in her piggy bank. The total amount of money in Susie's piggy bank will increase to $200+$40=$<<200+40=240>>240 #### 240 Benny bought 2 soft drinks for$ 4 each and 5 candy bars. He spent a total of 28 dollars. How much did each candy bar cost? Benny spent 2 * $4 = $<<2*4=8>>8 on soft drinks. Benny spent a total of $28 - $8 on soft drinks = $<<28-8=20>>20 on candy bars. Benny spent $20 / 5 candy bars = $<<20/5=4>>4 for each candy bar. #### 4 Jack has a stack of books that is 12 inches thick. He knows from experience that 80 pages is one inch thick. If he has 6 books, how many pages is each one on average? There are 960 pages because 80 x 12 = <<80*12=960>>960 Each book is 160 pages because 960 / 6 = <<960/6=160>>160 #### 160 Wickham is throwing a huge Christmas party. He invites 30 people. Everyone attends the party, and half of the guests bring a plus one (one other person). He plans to serve a 3-course meal for the guests. If he uses a new plate for every course, how many plates does he need in total for his guests? The number of guests that bring a plus one is 30 / 2 = <<30/2=15>>15 guests The total number of guests at the party, including the plus ones, is 30 + 15 = <<30+15=45>>45 guests Since there are 3 courses, Wickham will need 45 * 3 = <<45*3=135>>135 plates #### 135 There are some lions in Londolozi at first. Lion cubs are born at the rate of 5 per month and lions die at the rate of 1 per month. If there are 148 lions in Londolozi after 1 year, how many lions were there in Londolozi at first? There are 5-1=<<5-1=4>>4 more lions each month. There will be 4*12=<<4*12=48>>48 more lions after 1 year. There were 148-48=<<148-48=100>>100 lions in Londolozi at first. #### 100 John volunteers at a shelter twice a month for 3 hours at a time. How many hours does he volunteer per year? He volunteers 2*12=<<2*12=24>>24 times a year So he volunteers for 24*3=<<24*3=72>>72 hours #### 72 John puts $25 in his piggy bank every month for 2 years to save up for a vacation. He had to spend $400 from his piggy bank savings last week to repair his car. How many dollars are left in his piggy bank? He saved money for 2 years, which is equal to 12 x 2 = <<12*2=24>>24 months. The amount of money he saved is $25*24 = $<<25*24=600>>600. But he spent some money so there is $600 - $400 = <<600-400=200>>200 left. #### 200 Five coaster vans are used to transport students for their field trip. Each van carries 28 students, 60 of which are boys. How many are girls? There are a total of 5 vans x 28 students = <<5*28=140>>140 students. If 60 are boys, then 140 - 60 = <<140-60=80>>80 of these students are girls. #### 80
