MULTIPLE CHOICE QUESTION

Yesterday a chef used 68 eggs to make 8 chocolate souffles and 10 lemon meringue pies. The day before, he made 7 chocolate souffles and 10 lemon meringue pies, which used 62 eggs. How many eggs, does each dessert require? If (x) represents chocolate souffles and (y) represents lemon meringue pies, give the correct system of equations and the solution as an ordered pair.

8x + 10y = 68

7x + 10y = 62

( 2, 6 )

8x + 10y = 68

7x + 10y = 62

( 6, 2 )

7x + 10y = 68

8x + 10y = 62

( 5, 4 )

7x + 10y = 68

8x + 10y = 62

( 5, 3 )
