Mathematical ReasoningPregunta 59 de 120
A phone plan costs $30 per month plus $0.10 per text. Which expression gives the total monthly cost for t texts?
a.30t + 0.10
b.30.10t
c.30 + 0.10t
d.0.10 + 30t
Explicación
The fixed $30 fee is added to $0.10 times the number of texts t, giving 30 + 0.10t. The flat fee does not depend on t, while the per-text charge does. Translating word problems into expressions is a core algebra skill.
