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.
Percentage of U.S. Households in which Married
Couples Do Not Share the Same Faith

The formula
models the percentage of U.S. households with an interfaith marriage, I, x years after 1988. The formula
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 theses modes to solve Exercises 69 – 70.
a. In which years will more than 33% of U.S. households have an interfaith marriage?
b. In which years will more than 14% of U.S. households have a person of faith married to someone with no religion?
c. Based on your answers to parts (a) and (b), in which years will more than 33% of households have an interfaith marriage and more than 14% have a faith/no religion marriage?
d. Based on your answers to parts (a) and (b), in which years will more than 33% of households have an interfaith marriage or more than 14% have a faith/no religion marriage?
