A parent is buying two types of chocolate truffles for the children. The oldest child likes white chocolate (W), the younger two

valkas [14]

Answer:

Each dark chocolate tuffle was $6.

Step-by-step explanation:

This question can be solved by a system of equations.

Four white chocolate truffles (W) cost the same as three dark chocolate truffles (D).

So $4W = 3D$

The parent bought 3 white chocolate truffles(W) and 6 dark chocolate truffles (D), and spent $49.50.

$3W + 6D = 49.50$

$4W = 3D$

$D = \frac{4W}{3}$

$3W + 6D = 49.50$

$3W + 8W = 49.50$

$11W = 49.5$

$W = 4.5$

$D = \frac{4W}{3} = \frac{4*4.5}{3} = 6$

Each dark chocolate tuffle was $6.
