circle graph shows how a family spends its annual Income. If $27,300 is used for Auto and Insurance combined, what is the total annual income?
we know that
Auto -----> 12%
Insurance ----> 9%
so
Auto + Insurance=12+9=21%
that means
$27,300 represent 21%
therefore
Applying proportion
Find out how much represent 100%
27,300/21=x/100
solve for x
x=(27,300/21)*100
x=$130,000
the answer is $130,000
