Shelley is searching online for airline tickets. Two weeks ago the cost to fly from Boston to Orlando was $210. Now the cost is $305. What is the percent increase? What would be the percent increase if the airline charges and additional $50 baggage fee with the new ticket price?

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

not sure but it may be b, as i said i'm not sure.
