A ) = $ 0.18/oz = 4.68/26
b) = $0.19/oz = 2.66/14= 0.19
a is a better buy
9) for every 5 babies they need 1 babysitter, so for 40 babies they will need 8 babysitters.
V = π*r^2*h
(9000 in^3/min)*(10 min) = π*(72 in)^2*h
h = (90,000 in^3)/(5184π in^2) ≈ 5.5 in
Your answer would be -624 because 1-210-3= -212 then 3 times -212 +12= -624
I could be wrong but I think it’s 144,000m for the area
