The wages of 5 men and 6 boys amount to $114 per day. The wages of 7 men and 8 boys amount to $157 per day. Find the daily wages each man and each boy.

let the wages of men and boys be x and y respectively

then

5x+6y = 114

7x + 8y = 157

multiplying equation first by  4 and second by three and subtracting equations

20x + 24y = 456

21x + 24y =471

-x = -15

x= 15 men wages

substituting value of x in equation

5x + 6y = 114

5*15 + 6y = 114

6y = 114 -75

6y = 39

y = 6.5 each boys wages

Step-by-step explanation:

they will manufacture 8496 cars

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
