The survey of a manufacturing company producing a beverage and snacks was done. It was found that it sells orange drinks at 1.07 $a n d c h o c o c h i p c o o k i e s a t$ $0.78$ the maximum. Now, it was found that it had sold $57$ food items in total and earned about 45.87 $ of revenue. Find out the equations representing these two.

{\begin{matrix} x + y = 45.87 1.07 x + 0.78 y = 57 \end{matrix}

Solution

The correct option is C ${\begin{matrix} x + y = 57 1.07 x + 0.78 y = 45.87 \end{matrix}$
Let the company sell $x$ orange drinks and $y$ choc chip cookies.
The company sold $57$ food items.
Company sold orange drinks at 1.07 $a n d c h o c o c h i p c o o k i e s a t$ $0.78$
Then, as per given condition,
$x + y = 57$ ....(1)
$1.07 x + 0.78 y = 45.87$ ...(2)
