Clarence works at least 5 hours but not more than 7 hours. he earns $11.60 per hour. the function f(t)=11.6tf(t)=11.6t represents the amount of money he earns for working t hours.
what is the practical range of the function?

a: all multiples of 11.6 between 58 and 81.2, inclusive

b: all real numbers from 5 to 7, inclusive

c: all real numbers

d: all real numbers from 58 to 81.2, inclusive

the answer is  

a.

28 ft2

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.

you didn't give an question you just gave us a statement
