Answer 1

Answer:

x= 800

Step-by-step explanation:

total number of student be x

student using School transport= 40% of x

= 40/100× x

= 7/20 x

student not using School transport=520

total number of student= student using transport + student not using transport

x=7/20x + 520

x-7/20 x = 520

13/20 x = 520

x= 520 ÷ 13/20

x= 800
