Chad is driving 56 miles per hour. chad drove 168 miles in 3 hours. chad will drive 672 more miles. he continues to drive at the same rate. how many hours will it take chad to drive 672 miles?

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

what is the answer?
