You can put this solution on YOUR website!
Hourly rate= 10c+0.2*a, where c=number of children and a=age of baby sitter.
If baby sitter is 15, then 0.2*15=3
Hourly rate then equals
for c=1 10+3=$13
for c=2 20+3=$23, etc.
graph%28300%2C300%2C-5%2C5%2C-5%2C50%2C10x%2B3%29, where x-axis is number of children and y-axis is the hourly rate.
