A student scores 71 out of 100 on a test. If the maximum score on the next test is also 100 points, what score does the student need to maintain at least an average of 82?

93 points

Step-by-step explanation:

1. Set up the equation to find the mean/average.

2. (Solving)

Step 1: Multiply both sides by 2.

Step 2: Subtract 71 from both sides.

Therefore, the student needs to score at least 93 points on a test to maintain an average of 82.

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
