Richard gets his hair cut every 3 weeks. his hairdresser charges him $25
each time. a reasonable tip is 10%. richard pays him $28 each time. what
percent, to the nearest whole does richard tip his hairdresser?
a. 3%
b. 9%
c. 10%
d. 12%

D. 12%

Step-by-step explanation:

3/25=x/100

300=25x

x= 12%

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

5x+10 is the correct one
