The cash price of a refrigerator was $8000. Samantha wanted to buy the refrigerator but pay in installments. If she paid a deposit of $3000 and paid 30 equal monthly installments of $300 each, calculate how much money she would have saved by paying cash.

When Samantha paid $300 in 30 equal monthly installments, she paid a total of $

<<300*30=9000>>9000 Since the higher purchase is a deposit plus the total monthly installments, Samatha paid $3000+$9000=$<<3000+9000=12000>>12000 for the refrigerator on higher purchase. If she would have bought the refrigerator on the cash prize, Samantha would have paid $12000- to $8000= $<<12000-8000=4000>>4000 less. #### 4000 Jermaine, Terrence, and Emilee earn a total of $90. Jermaine earns $5 more than Terrence in a month. If Terrence earns $30, how much does Emilee earn? If Terrence earns 30 dollars, then Jermaine earns $30 + $5 = $<<30+5=35>>35 dollars. The total earnings of the two are $30 + $35 = $<<30+35=65>>65 dollars. Emilee earns $90 - $65 = $<<90-65=25>>25 dollars. #### 25 A store sells pencils and erasers. It has a rule that for every pencil you buy, you must buy 2 erasers which cost 1/2 the price of the pencils. If they sold 20 pencils and earned $80, how much do erasers cost? They sold 40 erasers because 20 x 2 = <<20*2=40>>40 Therefore 20(Pencil Price) + (1/2)(40 x Pencil Price) = 80 Therefore 40(Pencil Price) = 80 Therefore (Pencil Price) equals 2 because 80 / 40 = <<80/40=2>>2 An eraser costs $1 because 2 / 2 = <<2/2=1>>1 #### 1 The sum of the three angles of a triangle equals 250. The left angle is twice the right angle's value, and the right angle is 60 degrees. Find the value of the top angle? Since the left angle is twice the value of the right angle, the left angle is 60*2 = <<60*2=120>>120 degrees. The total value of the left and right angles is 120+60 = <<120+60=180>>180 degrees. Since the sum of the three angles is equal to 250, the other angle has a value of 250-180 = <<250-180=70>>70 degrees. #### 70 Adam went to a shop to buy some food for his journey. He bought 3 sandwiches, for $3 each, and a bottle of water for $2. How much did Adam pay for all the shopping? Adam bought 3 sandwiches, so he paid 3 * 3 = $<<3*3=9>>9 for them. In total Adam bought products for 2 + 9 = $<<2+9=11>>11. #### 11 Tamtam collected 65 shells in total. She got 13 purple shells, 8 pink shells, 18 yellow shells, and 12 blue shells. The remaining shells are color orange. How many orange shells are there? Tamtam has a total of 13 + 8 + 18 + 12 = <<13+8+18+12=51>>51 shells that are not orange. Therefore, Tamtam has a total of 65 – 51 = <<65-51=14>>14 orange shells. #### 14 Two hedgehogs found three baskets, each with 900 strawberries. The hedgehogs then each ate an equal number of strawberries. If 2/9 of the strawberries were remaining out of all the strawberries that were there, calculate the total number of strawberries that each hedgehog ate. The total number of strawberries in the three baskets is 3*900 = <<3*900=2700>>2700 If 2/9 of the strawberries were remaining out of all the strawberries after the hedgehogs ate some, there were 2/9*2700 = <<2/9*2700=600>>600 strawberries remaining. The total number of strawberries that the two hedgehogs ate is 2700-600 = <<2700-600=2100>>2100 strawberries. If the hedgehogs ate an equal number of strawberries, each ate 2100/2 = <<2100/2=1050>>1050 strawberries. #### 1050 Cynthia harvested 67 potatoes from her garden. After washing them, she cut 13 of them into wedges. She then halved the remaining potatoes and made french fries with one half, and potato chips with the other half. If one potato can be cut into 8 wedges or make 20 potato chips, how many more potato chips than wedges did Cynthia make? Cynthia was left with 67 -13 = <<67-13=54>>54 potatoes after making wedges. She used 54/2 = <<54/2=27>>27 potatoes to make potato chips. Cynthia made 13 x 8 = <<13*8=104>>104 wedges. She made 27 x 20 = <<27*20=540>>540 potato chips. Cynthia made 540 - 104 = <<540-104=436>>436 more potato chips than wedges. #### 436 There are 50 apples and 40 oranges in the cafeteria. If an apple costs $0.80 and an orange costs $0.50, how much does the cafeteria earn for apples and oranges if there are only 10 apples and 6 oranges left? Counting the remaining 10 apples. There were 50 - 10 = <<50-10=40>>40 apples sold. Counting the remaining 6 oranges. There were 40 - 6 = <<40-6=34>>34 oranges sold. The amount of sales for the apples is $0.8 x 40 = $<<0.8*40=32>>32. The amount of sales for the oranges is $0.5 x 34 = $<<0.5*34=17>>17. The cafeteria's total earnings are $32 + $17 = $<<32+17=49>>49. #### 49 Tomas is hoping to run a marathon next year, which is 26.3 miles. He knows that each month he trains, he can run twice as far as the month before. If he can run 3 miles during the first month of training, how many total months before the marathon should he start training to ensure he can run far enough? In the first month he can run 3 miles. In the second month he can run 6 miles because 3 x 2 = <<3*2=6>>6 In the third month he can run 12 miles because 6 x 2 = <<6*2=12>>12 In fourth month he can run 24 miles because 12 x 2 = <<12*2=24>>24 In fifth month he can run 48 miles because 24 x 2 = <<24*2=48>>48 He needs to start training 5 months ahead of time because 24 < 26.3 and 48>26.3. #### 5
