Chester must deliver ten bales of hay to Farmer Brown. Farmer Brown wants Chester to supply better quality hay and double the delivery of bales of hay. If the previous hay cost $15 per bale, and the better quality one cost $18 per bale, how much more money will Farmer Brown need to meet his own new requirements?

The hay previously cost $15 per bale so 10 bales would cost $15*10 = $

<<15*10=150>>150 Double 10 bales is 10*2 = <<10*2=20>>20 bales Better quality hay cost $18 per bale so 20 bales would cost $18*20 = $<<18*20=360>>360 Farmer Brown would need $360-$150 = $<<360-150=210>>210 more #### 210 Oliver is trying to decide between two different sized boxes of macaroni and cheese. He wants to know which is the better value, so instead of just looking at the overall price, he looks at the price per ounce. The larger box is 30 ounces and the smaller box is 20 ounces. The larger box costs $4.80. The smaller box costs $3.40. What is the price per ounce in cents of the box with the better value (lowest price per ounce)? The larger box of macaroni and cheese costs 480 cents / 30 ounces = <<480/30=16>>16 cents per ounce. The smaller box of macaroni and cheese costs 340 cents / 20 ounces = <<340/20=17>>17 cents per ounce. The lower price per ounce is <<16=16>>16 cents. #### 16 Roland needs a length of thread to complete an exercise. He has a 12cm long thread but his teacher says he needs an additional three-quarters of what he has. What is the total length required? An additional three-quarters of 12cm is needed which is 12cm*(3/4) = <<12*(3/4)=9>>9cm The total length required is 12cm+9cm = <<12+9=21>>21cm #### 21 Donald drinks 3 more than twice the number of juice bottles Paul drinks in one day. If Paul drinks 3 bottles of juice per day, how many bottles does Donald drink per day? Twice the number of bottles Paul drinks in one day is 3 * 2 = <<3*2=6>>6 bottles. So, the number of bottles that Donald drinks in one day is 6 + 3 = <<6+3=9>>9 bottles. #### 9 During the Easter egg hunt, Kevin found 5 eggs, Bonnie found 13 eggs, George found 9 and Cheryl found 56. How many more eggs did Cheryl find than the other three children found? We know that Kevin found 5, Bonnie found 13 and George found 9 so 5+13+9 = <<5+13+9=27>>27 Cheryl found 56 eggs while the others found 27 eggs so 56-27 = <<56-27=29>>29 more eggs #### 29 James scored 13 field goals worth 3 points and 20 shots worth two points. How many total points did he score? The field goals were worth 3*13=<<3*13=39>>39 points The two-point shots were worth 2*20=<<2*20=40>>40 points So the total score is 39+40=<<39+40=79>>79 points #### 79 Rebecca bought 22 items for her camping trip, including tent stakes, packets of drink mix, and bottles of water. She bought 3 times as many packets of drink mix as tent stakes. She also bought 2 more bottles of water than she did tent stakes. How many tent stakes did she buy? Let x represent the number of tent stakes Drink Mix: 3x Bottles of Water: x+2 Total: x+3x+x+2=22 5x+2=22 5x=20 x=<<4=4>>4 tent stakes #### 4 Bingo has two dogs. On average, they walk a total of 70 miles a week. The first dog walks an average of 2 miles a day. How many miles a day does the other dog average? The first dog walks 14 miles in a week because 7 x 2 = <<7*2=14>>14 The second dog walks 56 miles in a week because 70 - 14 = <<70-14=56>>56 The second dog walks an average of 8 miles a day because 56 / 7 = <<56/7=8>>8 #### 8 A store owner ordered 20 cases of bottles of soda in April and 30 cases in May. There are 20 bottles per case. How many bottles of soda did the store owner order in April and May? The store owner ordered a total of 20 + 30 = <<20+30=50>>50 cases. This is equal to 50 x 20 = <<50*20=1000>>1000 bottles of soda. #### 1000 Louise is organizing her pencils, and decides she wants her boxes arranged by color. Each box holds 20 pencils each. She has 20 red pencils, twice as many blue pencils, 40 yellow pencils, and has as many green pencils as she has red and blue pencils combined. How many boxes does Louise need? Louise has 20 red pencils * 2 = <<20*2=40>>40 blue pencils. She therefore has 20 red pencils + 40 blue pencils = <<20+40=60>>60 green pencils. In total, she has 20 red pencils + 40 blue pencils + 60 green pencils + 40 yellow pencils = <<20+40+60+40=160>>160 pencils. As each box holds 20 pencils, she needs 160 pencils / 20 pencils/box = <<160/20=8>>8 boxes. #### 8
