In more U.S. marriages, spouses have different faiths. The bar graph shows the percentage of households with an interfaith marriage in 1988 and 2012. Also shown is the percentage of households in which a person of faith is married to someone with no religion. The formula I = (1/4)x + 26. models the percentage of U.S. households with an interfaith marriage, I, x years after 1988. The formula N = (1/4)x + 6 models the percentage of U.S. households in which a person of faith is married to someone with no religion, N, x years after 1988. Use these models to solve:
