Answer:
Step-by-step explanation:
the population is all students enrolled in the school district
Total amount = $80
Amount spent on Monday = 3/5 x 80 = $48
Amount remaining = $80 - $48 = $32
The money is spent over 5 days:
5 days = $32
1 day = $32 ÷ 5 = $6.40
Answer: She spent $6.40 on each of the 5 days.
Answer:
p+5+7=p+12
p/(p+12) ×900=120
900p=120(p+12)
90p=12(p+12)
90p=12p+144
90p-12p=144
78p=144
p=144/78
I would appreciate if my answer is chosen as a brainliest answer
To solve for n:
n/3+5=7
Subtract 5 from both sides.
n/3=2
Multiply both sides by 3.
n=6
Hope this helps! :)
