Question

For her cell phone plan, Kayla pays $45 Per month plus $.10 per text. She wants to keep her bill under $65 per month. Which inequality represents the number of text, t, Kayla can send each month while staying within her budget? PICK A CHOICE! A) t < 200 B) t > 200

C) t < 400 D) t < 400.

Answer 1

So the bill would have to be <$65, so $45 (the monthly that doesn't change) + $.10 x t would equal that.

45+(.10xt)<65 simplify the eguation
45+.1t<65 subtract both sides by 45
.1t<20 divide both sides by .1
t<200
