Answer:
$25.50
Step-by-step explanation:
So we have a 15% off coupon. We can multiply 25×.85 to find our new price.
Our total is now $21.25
Now to find the tip do $21.25 +(.2 × 21.25)
*The .2 is 20 percent of our discount price.*
We then get $25.50
Answer:
Step-by-step explanation:
1. This paragraph describes an observational study.
It is not a controlled experiment because the guidance counselors didn't plan to separate the students into 2 groups and then observe the results. They instead checked records.
2. The students who took Latin are the treatment group.
3. The fact that students decided on their own to take Latin is a confounding factor.
4. The students who did not take Latin are the placebo or control group.
1.5 miles/30 minutes is your unit rate. If you multiply the rate by 2 you would get 3 miles/hour.
So your final answer would be 3 miles per hour.
Hope this helps.
