The label on the car's antifreeze container claims to protect the car between −30°c and 130°c. to convert celsius temperature to fahrenheit temperature, the formula is:
c = 5/9(f − 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car.

a.) -30> 5/9(f-32)> 130; -22> f> 266

b.) -30< 5/9(f-32)< 130; -22
c.) -30< 5/9(f-32); -22
d.) 5/9(f-32)< 130; f< 266

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.

to convert it in decimal, we divide it by 100, we get

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