Question

PLEASE HELP

Jackie has two jobs. She earns $14/h in Job A and $16/h in Job B. She would like to earn $560 in a week. Let a represent the number of hours she works in Job A, and let b represent the number of hours she works in Job B.



Which function relates the number of hours she works in Job B to the number of the hours she works in Job A?

Answer 1

560=14a+16b
560-14a=16b
b=(560-14a)/16
b=35-7/8a or b=-7/8a+35
so the answer is B
