Subtract 3 from both sides: 4x = 16; divide by 4: x = 4.

Question 4: A vending machine charges $1.25 per snack. Which expression shows the cost of s snacks?

1.25s (Correct answer)
1.25 ÷ s
s ÷ 1.25
s + 1.25

Correct answer: 1.25s

Multiplying the price per snack by the number of snacks gives 1.25s.

Question 5: Someone's unattended luggage slides out of an open hatchway aboard a helicopter at 30,000 feet. How much time does a recovery crew have to catch the luggage before it lands? (Assume the baggage is falling at 145 feet per second at its final velocity.)

2 minutes and 45 seconds
3 minutes and 7 seconds
2 minutes
3 minutes and 27 seconds (Correct answer)

Correct answer: 3 minutes and 27 seconds

To find the time it takes for the luggage to fall, divide the total distance by the falling speed. Time = Distance / Speed = 30,000 feet / 145 feet/second. This calculation yields approximately 206.896 seconds. Converting this to minutes and seconds (206.896 / 60) gives 3 minutes and approximately 26.9 seconds, which rounds to 3 minutes and 27 seconds.

Question 6: What is the primary purpose of informational text as assessed on the CAASPP?
