Answer:
I think it should be A.
Step-by-step explanation:
8-1 is 7 which is very close to 6, and it says they are similar so this could work.
You can solve a system of three equations by multiplying each equation by a number that allows you to add or suvtract the same equation together by eliminating the x or y variable
180/60 = the number of student for 1%
180/60 = 3
so 1% of the school's population is 3 students
so, 3 x 100 = 300 students
and to check:
300 x .60 = 180
so, the total population of the school is 300
