Answer:

71%

Step-by-step explanation:

I think the easiest way to think of this is to pretend that there are a total of 100 students at the high school, so that means the amount of people who work part time is 45% of 100 = 45 people. If 60% of those students love math, you do 0.6 * 45 = 27 people.

Next, 80% of the students who do not have a part time job (100 - 45 = 55) love math, so 0.8 * 55 = 44 people.

44 + 27 = 71, so the percent is 71/100 = 71%.

let me know if any part of that doesn't make sense

J.c. Penny sells a timed watch for $139.99 that cost$89.97. J.C. Penny’s percent of markup based on the selling price is:
vodka [1.7K]
So it cost them 89.97 and they're selling it for 139.99, the difference is 50.02.

so, the markup is 50.02, if we take 89.97 to be the 100%, how much is 50.02 off of that in percentage?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
89.97&100\\
50.02&p
\end{array}\implies\cfrac{89.97}{50.02}=\cfrac{100}{p}\implies p=\cfrac{50.02\cdot 100}{89.97}
