$60 ÷ $15 = 4
$9 × 4 = $36
he saved $36 when he earned $60
This number has decimal digits, so it surely is not integer. This rules out options A and D.
Since the decimal digits are finitely many, the number is rational (you can write it as 1723/1000)
So, the answer is B
Answer:
58%
Step-by-step explanation:
Out of 60 students who take math, 35 of them will also have science. The desired probability is ...
35/60 = 0.58333... ≈ 58%
__
More formally, ...
P(S | M) = P(S&M)/P(M)
= 35%/60% = 7/12 ≈ 58%
