I'm asuming you did a typo from a previous quesiton I see that it is a dollar sign
$12 per hour
for 15 hourse, just multiply $12 by 15 because per hour means per 1 hour
15 times $12=$180
answer is $180
If C is the MIDPOINT of BD, and BD equals 12, then what does CD equal?
AD = AC+CD, so you only need to find length of CD and add length of AC (which you already have) to it.
Hope this helps
473x6= 2,838
the answer should be 2,838?
