A slice of pizza costs $3.19 and a drink costs $r. The cost of a slice of pizza and a drink together is $5.61 Complete and make the equation that represents the cost of a drink.
Let's represent the cost of a drink as $d.
Since a slice of pizza costs $3.19, the total cost of a slice of pizza and a drink together is $3.19 + $d.
We also know that the total cost of a slice of pizza and a drink together is $5.61.
Hence, we can write the equation:
$3.19 + $d = $5.61
