Answer:
-$5.27 per day
Step-by-step explanation:
1st. $300
6th. $273.65
19th. $205.14
25th. $173.52
28th. $157.71
Lets use the one that has the least amount of days separated to make it easier
28th and 25th
157.71 - 173.52 = -15.81
count how many days are separated (3)
then divide that to what the amount is
-15.81 / 3 = -$5.27 per day
Answer:
500 students in the school
Step-by-step explanation:
100 - 68% = 32%
boys percentage 68%
girls percentage 32%
difference 68 - 32 = 36% = 180
36 ÷ 18 = 2 × 50 = 100
180 ÷ 18 = 10 × 50 = 500
