For this we need to do (1530/3000)*100
1530/3000 is the same as 153/300 which is the same as 51/100
Therefore the total percentage is 0.51*100 = 51%
1.4 because you divide 7.45 by 5.51 and you get 1.35 which would be rounded to 1.4

Answer:
2 hours.
Step-by-step explanation:
Money earned for 14 hours of life-guarding = 14*18 = $252. If he worked another 5 hours to make the maximum of 19 he would earn 252 + 5*9
= $297 but he wants to work a minimum of hours for a minimum of 270.
Thus we have the inequality:
252 + 9x ≤ 270
9x ≤ 18
x ≤ 2.
So the number of hours he must do clearing tables = 2.
Since ms. watson’s class read for a total of 450 hours, we can calculate the amount of hours the mr gerk’s class read by: 450*2/3, which equals 300. Then we know Miss rupp’s class read twice the number of hours read by mr. gerk’s class so that’s 600 hours.
finally in order to calculate the average number of hours: (450+300+600) /90=15
