Determine whether each sample may be biased. Explain: A disc jockey asks the first 10 listeners who call in if they liked the last song that was played

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

150.6

all i did was i multiplied 5.02 by 30
