Jack and Jill both begin working new jobs for the summer. Jack is offered $18 per hour and will also be given $699 up front for accepting the job. Jill is offered $20 per hour for her work, with no up front bonus. After how many hours of work will Jack and Jill have earned the same (or equal) amount of money? ANSWER ASAP PLZ

i believe a. 12x≥120 is the answer

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.
