Answer: $3.16.
Step-by-step explanation:
You want to leave a 15% tip on a meal that cost $21.05.
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $21.05 meal cost is.This is always done by multiplying 0.15 by $21.05, or
0.15 x $21.05=$3.16.
So, the amount of tip you are going to leave is $3.16.
Answer:
d = 48t will represent the distance 'd' traveled in 't' hours.
Step-by-step explanation:
Jason leaves Detroit at 2:00 PM and passes through Ann Arbor at 2:50 PM which is 40 mi distant from Detroit.
Speed during this journey was constant.
Jason traveled 40 mi in 50 minutes or hours from Detroit to Ann Arbor.
By the formula,
Speed =
Speed =
= 48 mi per hour
If he travels 'd' miles in 't' hours then by the formula of speed,
48 =
d = 48t
