Question 55223
In 2000 there were 48.5 births per 1000 females 15 to 19 years of age. This birth rate is 4/5 of the birth rate for teenagers in 1991.
:
a)Write an equation and solve it to find the birth rate for teenagers in 1991.
{{{48.5/1000=(4/5)X}}}
{{{.0485=(4/5)X}}}
{{{(5/4)(.0485)=(5/4)(4/5)X}}}
{{{.060625=X}}}
The birthrate was .061 or about .061*100%=6.1% (if you need percentage.)
:
b)What will be the birth rate for teenagers in 1996, if there were 55 births per 1000 females?
{{{55/1000=.055}}}
or .055*100%=5.5% (if you need percentage.)
Happy Calculating!!!
