In 2013, Hubert and Madison purchased Series EE bonds, and in 2017 redeemed the bonds, receiving $660 of interest and $840 of principal. Their income from other sources totaled $38,000. They paid $2,000 in tuition and fees for their dependent daughter. Their daughter is a qualified student at State University. (The proceeds from the Series EE bonds were used to pay the tuition and fees.)

Exclusion phaseouts: Phaseout occurs when the combined amount of principal and interest received during the year exceeds the net qualified educational expenses and the taxpayer's modified adjusted gross income is over $78,150 ($117,250 for married individuals filing a joint return). The exclusion is fully phased-out for taxpayers whose 2017 modified AGI is more than $93,150 ($147,250 for married individuals filing a joint return).

Requirement a. Assuming the daughter received the $3,300 scholarship and that the parents' income from other sources is $120,830, how much of the interest is excludable?
