Answer:
24 walls per volunteers
Step-by-step explanation:
given that there are 864 walls and that there are 36 volunteers
if the walls are divided evenly over the 36 volunteers,
each volunteer would paint,
= 864 walls ÷ 36 volunteers
= 24 walls per volunteers
543
let x= total salary
0.25x=135.75
x=543
5,265000
390,00 x9%=351000
351000 x15==5,2650000
