A)

150 were surveyed, possible outcomes, and 132 said they prefer dogs, favorable outcomes, 132/150 or 22/25 or 0.88, now 0.88 * 100 is just 88, namely 88% is the probability.

b)

since we know is 88%, what is 88% of 100? (88/100) * 100, 0.88 * 100, or just 88 students.

c)

18/150 or 3/25 or 0.12 namely 12%,

what's 12% of 300? (12/100) * 300, or 0.12 * 300, so just 36 students.

A high school athletic department bought 40 soccer uniforms at a cost of $3,000. After soccer season they returned some uniforms

Interesting problem.

First - let's figure cost of each uniform at purchase.

3,000/40 = $75 each

When some uniforms were returned at $40 - there was a difference of $35 in what they paid and what they rec'd in return. ($75 - 35 = $40)
