Cecil has a credit card that uses the adjusted balance method. for the first 10

days of one of his 30-day billing cycles, his balance was $340. he then made

a purchase for $290, so his balance jumped to $630, and it remained that

amount for the next 10 days. cecil then made a payment of $150, so his

balance for the last 10 days of the billing cycle was $480. if his credit card's

apr is 19%, which of these expressions could be used to calculate the

amount cecil was charged in interest for the billing cycle?

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

step-by-step explanation:
