sergey [27]

Answer:

100

Step-by-step explanation:

Ratio is a fraction, so ratio of boys to girls would be written as [let boys be "b" and girls be "g"]:

$\frac{b}{g}=\frac{2}{7}$

Also, there are 250 more girls than boys, so we can write:

g = 250 + b

Lets substitute this into "g" of the ratio we wrote and cross mulitply and solve for b:

$\frac{b}{g}=\frac{2}{7}\\\frac{b}{250+b}=\frac{2}{7}\\7b=2(250+b)\\7b=500+2b\\5b=500\\b=\frac{500}{5}=100$

The number of boys = 100

Lina20 [59]

Answer:

16%

Step-by-step explanation:

The data provided on brand purchased by age group is.

$\begin{array}{ccc}Age&Buick&Honda\\Under\ 40&6&17\\40\ or\ older&19&8\end{array}$

A total of 50 cars were sold this month.

Since the number of buyers 40 years or older that purchased a Honda is 8, the percentage is:

$P=\frac{8}{50}=0.16=16\%$

16% of buyers were 40 years or older and purchased a Honda.
