Betty is growing parsnips in her vegetable garden. When the parsnips are grown, they are harvested and bundled into boxes that can hold up to 20 parsnips each. Each harvest, three-quarters of the boxes are full, and the remaining boxes are half-full. She gets an average of 20 boxes each harvest. How many parsnips does Betty grow in an average harvest?
How many boxes are half-full? ** If three-quarters of the boxes are full, then 1 – ¾ = ¼ of the boxes are half-full.
How many boxes are half-full? ** On average, each harvest therefore has 20 boxes * 0.25 = <<20*0.25=5>>5 boxes that are half-full.
How many boxes are full? ** This leaves 20 total boxes – 5 half-full boxes = <<20-5=15>>15 full boxes.
How many parsnips do half-full boxes hold? ** Half-full boxes hold 20 parsnips / 2 = <<20/2=10>>10 parsnips each.
How many parsnips do the half-full boxes hold? ** In total, the half-full boxes, therefore, hold 5 boxes * 10 parsnips = <<5*10=50>>50 parsnips.
How many parsnips do full boxes hold? ** The full boxes hold a total of 15 boxes * 20 parsnips = <<15*20=300>>300 parsnips.
How many parsnips does Betty grow in an average harvest? ** So Betty harvests a total of 50 + 300 = <<50+300=350>>350 parsnips in an average harvest.
