The answer would be 18 because the whole number is 17 and the fraction is 5/8, which is more than 1/2 so you would round up, making the next whole number 18.
They have 121 apples all together. 110+5=115, 115+6=121
so every 3 orange picks there are 2 green picks so 6 orange picks leads to 4 green pick and just keep adding to each side. 9 orange picks is 6 green picks, 12 orange picks is 8 green picks. Therefore you add 3 to 12 and get 15 which means 15 orange picks is your answer.
A: y=1500x + 2000
For B, just times 1500 by 1 through 6 plus the 2000
divide 400 by 24
400 / 24 = 16.666
so they would need to buy 17 crates
