Cindy is preparing for a race. In one practice, she ran 5 miles in 30 minutes. In other practice, she ran 3 miles in 23 minutes. What is Cindy's average rate of change (speed/slope)? Express your answer in context and as a unit rate (rate of change).

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.
