Cost of each videotape is $14.99 and you buy total 4 videotapes.

And the cost of each DVD is $19.99, and you bought 3 DVDs.

Consider, the expression for the total cost of the movies,

$(4×14.99)+(3×19.99)$

The value of the expression for the total cost of the movies,

$\begin{array}{l}(4×14.99)+(3×19.99)\\ (4×14.99)+(3×19.99)=\left(59.96\right)+\left(59.97\right)\left[\text{multiplywithinparentheses}\right]\\ (4×14.99)+(3×19.99)=119.93\left[\text{add}\right]\\ \end{array}$

Therefore, the value of the expression for the total cost of the movies,

$(4×14.99)+(3×19.99)=119.93$
