I do believe it is 3+x=y. y=Longest piece of wood.
*First you want to find out how much he makes a day
15x2=30
*so for 2 weeks he made $30 a day
*Obliviously there are 7 days a week so 7x2=14
*Now multiply 14x30= $420
hope I helped!
Step-by-step explanation:
P(black or yellow) = P(black) + P(yellow) − P(black and yellow)
P(black or yellow) = 1/25 + 1/5 − 0
P(black or yellow) = 6/25
