In May, Mrs. Smith's earnings were 60% of the Smith family's total income. In June Mrs. Smith earned 20 percent more than in May. If the rest of the family's income was the same both monts, then, in June, Mrs. Smith's earnings were approximately what percent of the Smith family's total income?

M = Mrs Smith's income for May
J = Mrs Smith's income for June
