Given that,
r₁ = 15 inches, r₂ = 6 inches
The area of the cylinder is given by :
The ratio of surface areas of two cylinders,
Hence, the required ratio is 4:25.
30% off 25: multiply 25 by .30 to find 30%: 7.5. Now subtract that from the sales price: 25-7.5=17.5
Do the same for store B: .40•30=12. 30-12=18.
So store A is better by $.50 :) hope this helps :)
