Question

gemma has 3 rose bushes, each with the same number of roses. she picks 4 of the roses. there are 20 roses left on the rose bushes. how many roses were left on each rose bush? write two equations with letters for the unknown.

Answer 1

Each bush has 8 roses.

If she took 4 roses and is left with 20, that means there was 24 roses in total.

Since there is an equal number of roses on all 3 bushes, you divide the 24 roses by 3 bushes.
