Kirsty needs to hire a plumber to fix her house. The plumber charges 2425 dollars for every hour of labor and 3678 dollars for equipment. If the plumber works for 3.510 hours, how many dollars (in base ten) will Kirsty owe the plumber?
242 base 5 = 2 x 25 + 4 x 5 + 2 x 1 = 72 per hour 72 x 3.5 = 252 dollars
PLUS 367 base 8 = 64 x 3 + 6 x 8 + 7 = 247
247 + 252 = $
