Emily has twice the number of high school credits Spencer has, meaning Spencer has 20 / 2 = 10 high school credits. Altogether, the three have 40 + 20 + 10 = 70 high school credits. Twice the total number of high school credits the three have is 2 * 70 = 140. <ibo> Nkọwa: Ọ bụrụ na Emily nwere kredit iri abụọ, na Aria nwere okpukpu abụọ, mgbe ahụ Aria nwere 2 * 20 = kredit iri anọ nke ụlọ akwụkwọ sekọndrị.
