last summer, at camp okey fun okey, the ratio of the number of boy campers to the number of the girl campers was 8:7 if there were a total of 195 campers, how many boy campers were there? how many girl campers?

Verified Answer :

There are 104 boys and 91 girls. 104+91=195        104:91 = 8:7

Defining variables we have:

x: number of boys

y: number of girls

We then have the following system of equations:

 \(\frac{x}{y} = \frac{8}{7}\)

\(x + y = 195\)

Rewriting the first equation we have:

 \(x = \frac{8}{7}y\)

Substituting in the second equation:

 \(\frac{8}{7}y + y = 195\)

By clearing the variable we have:

\(8y + 7y = 1365  15y = 1365\)

\(y =\frac{1365}{15}   y = 91\)

Then the value of x is:

\(x = 195 - y  x = 195 - 91  x = 104\)

Answer:

104 boys campers

91 girls campers
