Question

You buy 4 videotapes for \(14.99 each and 3 DVDs for \)19.99 each. Find the total cost of the movies.

Short answer

The total cost of movies is $119.93.

Step-by-step solution

Step-1 – Order of operations

To evaluate any expression involving more than one operation, follow the below order of operations:

• First evaluate expressions inside grouping symbols like parentheses ( ) or brackets [ ].
• Evaluate the exponents.
• Perform Multiplication and division from left to right.
• Perform addition and subtraction from left to right.

Step-2 – Given

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.

Step-3 – Evaluate the expression

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

$(4\times 14.99)+(3\times 19.99)$

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

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

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

$(4\times 14.99)+(3\times 19.99)=119.93$
