To estimate the proportion of contaminated soft-drink dispensers in a community in virginia, researchers randomly sampled 30 dispensers and found 5 to be contaminated with chryseobacterium meningosepticum

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

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

she would want to sell 10 full-year subscriptions and at least 9 half-year subscriptions to get a total of at least $300.
