April is donating plant pots to a local school for their new garden. They ask for 30 plant pots for the daisies, and twice as many for the roses. April had already bought 100 plant pots from the garden center before she knew how many she needed. How many plant pots does April have left over?

How many plant pots does the school want for the roses? ** For the roses, the school wants 30 * 2 = <<30*2=60>>60 plant pots.
How many plant pots does April give the school? ** This means she is giving the school 60 plant pots for roses + 30 plant pots for daisies = <<60+30=90>>90 plant pots.
How many plant pots does April have left over? ** So in total, Alice has 100 – 90 = <<100-90=10>>10 plant pots left over.
