A slice of pizza costs $3.19 and a drink costs $x. The cost of a slice of pizza and a drink together is $5.61. Complete and solve the equation that represents the cost of a drink.
x + 3.19 = ___
x = ___
what is ___?
x + 3.19 = 5.61
Subtracting 3.19 from both sides of the equation:
x = 5.61 - 3.19
x = 2.42
Therefore, the cost of a drink is $2.42.
