One cell phone plan charges 20$ per month plus$0.15 per minute used. a second cell phone plane charges $35 per month plus $0.10 per minute used. write and solve an equation to find the number of minutes youmust talk to have the same cost for both calling plans. i suck at word problems.

300 minutes aka 5 hours

Step-by-step explanation: see paper attached (:

john has 55 candy left.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
