Answer: C: Expression B and D
Step-by-step explanation:
Say the item is $100. 20% of 100 is equal to 100 (20/100)
When you simplify, it equals 20. So 20% of 100 is 20. This $20 is the amount of discount you receive.
So you have to subtract $20 from the $100 to find the sale price. The sale price is $80.
Now plug in 100 for p in each equation. The equation that equals 80 is the answer.
Only equation B and D equals 80 when 100 is plugged in.
Answer:
A. 3 hours 20 minutes
Step-by-step explanation:
The distance divided by the speed gives you the time.
(234 miles)/(70 mph) = 3.343 hours.
3.343 hours is decimal hours. We need hours and minutes.
1 hour = 60 minutes. We separate the whole hours from the decimal part of the hours, and we multiply the decimal part of the hours by 60 to find minutes.
3.343 hours =
= 3 hours + 0.343 hours
= 3 hours + 0.343 hours * 60 minutes/hour =
= 3 hours + 20.6 minutes
The closest answer is:
A. 3 hours 20 minutes
