Helpppp Please Biologyyyy!?

Problem:in a wildflower population, the allele for pink flowers is A and white flowers is a (which is a recessive to A). If there are 500 plants in which 180 areAA(zygous dominant), 200 are Aa (heterozygous), and 120 are aa(zygous recessive), what are the genotype and allele frequencies?
