Calculate the 1st quartile of the data set below: 53, 54, 71, 95, 108, 110, 115, 120, 128, 128, 129, 141, 143, 158, 193

yo answer should be 6 if im not mistaken

step-by-step explanation:

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
