In eastern gray squirrels, sciurus carolinensis, the allele for black fur (b) is dominant to the allele for gray fur (b). in a particular population of gray squirrels, 64% have black fur and 36% have gray fur. a researcher calculated the allelic frequencies to be b=0.4 and b=0.6. five years later, the researcher returned to the location and determined the allelic frequencies within the squirrel population to be b=0.6 and b=0.4.

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )

718 strawberries is the answer
