If the parent bought 5 white chocolate truffles(W) and 10 dark chocolate truffles (D), and spent $60.00, how much was each dark chocolate truffle?

Answer:

The price of single dark chocolate truffle was $4.5.

Step-by-step explanation:

Let the price of white chocolate be x and dark chocolate be y.

Three white chocolate truffles cost the same as two dark chocolate truffles. Mathematically can be written as:

[tex]3x=2y[/tex]...[1]

Number of white chocolate truffles = 5

Cost of 5 white chocolate truffles = 5x

Number of dark chocolate truffles = 10

Cost of 10 dark chocolate truffles = 10y

Total money spend on  5 white chocolate truffles and 10 dark chocolate truffles= $60.00

[tex]5x+10y=\$60.00[/tex]..[2]

Solving [1] ans [2] ,we get :

x = $3

y = $4.5

The price of single dark chocolate truffle was $4.5.
