D. $1.25
Explanation:
Let x be the amount of 1 piece of gum and y be amount of 1 candy bar.
4x + y = 2.75
4x + 6y = 6.50 ... [Multiplying the second eq. by 2]
-5y = -3.75
5y = 3.75
y =
Now substituting the value of y in the first eq. we get :
So now as asked x + y
= 0.50$ + 0.75$
= (0.50 + 0.75) $
= 1.25$
Thus Option D. 1.25$ is correct.
