Each tree in an orchard containing 2,650 trees requires 210 grams of fertiliizer. At $1.25 per kilogram of fertilizer, how much does it cost to fertilize the orchard?

Calculate the total fertilizer needed:
Total fertilizer needed = Number of trees * grams of fertilizer per tree
Total fertilizer needed = 2650 * 210
Total fertilizer needed = 556500 grams

1 kilogram = 1000 grams, so we convert our 556500 grams to kilograms:
kilograms of fertilizer = grams of fertilizer / 1000
kilograms of fertilizer = 556500/1000
kilograms of fertilizer = 556.5

Calculate fertilizer cost:
Fertilizer cost = kilograms of fertilizer * cost per kilogram
Fertilizer cost = 556.5 * 1.25
Fertilizer cost = 695.63
