Harper surveyed every fourth student coming back from lunch in 6th grade to see what sport they preferred to participate in for field day. Out of the 28 students she surveyed, 8 stated that they would prefer to play volleyball. If there are a total of 392 students in 6th grade, how many would you expect to prefer volleyball?"​

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

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
