FSA Algebraic Thinking 3

Question 1

Sarah earns $9 per hour. Which inequality shows how many hours (h) she must work to earn at least $63?

Accepted Answer

9h ≥ 63

Answer

'At least $63' means her earnings must be $63 or more, so the inequality is 9h ≥ 63.

Question 2

Two friends split a restaurant bill equally, and each pays $14. Which equation finds the total bill (b)?

Accepted Answer

b ÷ 2 = 14

Answer

If the bill is divided equally between 2 people and each pays $14, then b ÷ 2 = 14, giving a total of $28.

Question 3

The perimeter of a square is given by P = 4s, where s is the side length. If the perimeter is 36 inches, what is the side length?

Accepted Answer

9 inches

Answer

Set up the equation 4s = 36 and divide both sides by 4 to get s = 9 inches.

Question 4

A store sells notebooks for $3 each. Which expression shows the money remaining after buying n notebooks if you start with $20?

Accepted Answer

20 - 3n

Answer

You start with $20 and spend $3 per notebook, so money remaining = 20 - 3n.

Question 5

Which equation has a solution of x = -3?

Accepted Answer

x + 5 = 2

Answer

Substituting x = -3 into x + 5 = 2 gives -3 + 5 = 2, which is a true statement.
