16 cupcakes is the answer
Answer:
m=4, -1
Step-by-step explanation:
if i am interpreting this correctly, you are wanting to find at what value of m would the solution be zero.
so, there are two expressions that can cause an answer of 0.
1) if 0=m2-4
so solve for m2, and you get 4=m2
2) if 0=m2+1
solve for m2, and you get -1=m2
you can check your work by plugging the values back into the equation.
P(m)=(4-4)(4+1)
=(0)(5)
=0
and
P(m)=(-1-4)(-1+1)
=(5)(0)
=0
4x = 400 —> x = 100 weeks 1-4
400 + 2y = 500
2y = 100
y = 50 weeks 5-6
Last three weeks
Week 4 100
Week 5 50
