The ACT Scale is composed of a number of subtests. On one subtest, the raw scores have a mean of 27 and a standard deviation of 3. Assuming these raw scores form a normal distribution. What score represents the 97th percentile 197% and below?
a. x=33
b. x=30
c. x=31
d. x=35

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

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
