Answer:
The tip would be $1.44, so the total would be $13.44
Step-by-step explanation:
To find the tip you take the bill ($12), and multiply it by the percent of tip given (12%), but it has to be in decimal form. 12% in decimal form is .12. 12 times .12 is 1.44. Add $12 to that to get $13.44.
First, add together the costs for buying their own stuff. 250+135+69+25=479.
Then figure for the professional costs. Put it in perspective of a year. 45*11+75=570.
Then subtract. Professional- DIY. 570-479=91.
$91 is about 2 months worth of work. So a year has 12 months.
12-2=10
Answer:10 months
