A study found that 9% of dog owners brush their dogs teeth. Of 578 dog owners, about how many would be expected to brush their dogs teeth? Explain. Please help I am confused
9 percent of 578 is 52.02. 578/x=100/9 (578/x)*x=(100/9)*x - we multiply both sides of the equation by x 578=11.111111111111*x - we divide both sides of the equation by (11.111111111111) to get x 578/11.111111111111=x 52.02=x x=52.02
