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?

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

answer: 0.1,0.85

step-by-step explanation:

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.

slope= 1

y-inter slope= 0
