Jamila and akiko had the same amount of money to spend. after jamila spent $33 and akiko spent
$42, jamila had 4 times as much money left as akiko. how much money did each of them have in
the beginning?

$45

Step-by-step explanation: Let the amount of money be x ,

Then , after Jamila spent $33 , the remaining money is x-33,

Also , after Akiko spent $42 , the remaining money is x- 42,

since Jamila is now having 4 times as much money left as Akiko, we have

x - 33 = 4 ( x - 42)

x - 33 = 4x - 168

-33+168 = 4x - x

135 = 3x

Therefore ,

x = 45

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
