The correct answer is A) 0.5%
—————————————————————
To find the total amount of employees, add all values in the boxes together:
758 + 530 + 7 + 105 = 1,400
7 employees out of 1,400 employees walk to work
7/1400 = x/100
Cross multiply
7(100) = 1400(x)
700 = 1400x
7 = 14x
x = .5
.5% of the employees walk to work
Hope this helps :)
