The answer would be 12oz since there is 4 bottles of 3oz perfume and all together that would add too 12oz.
(totalPrice-discountedPrice)/totalPrice x 100
so that would be:
(380-300)/380 x100 = 21%
3(x-9)=-39
3x-27=-39
+27 +27
3x=-12
/3 /3
x=-4
Answer:
It can travel 288 miles on 12 gallons.
Step-by-step explanation:
The car can travel 96 miles on 4 gallons. 12 gallons is 3 times more than 4 gallons. This means that the miles the car can travel on 12 gallons is also 3 times more than it can travel on 4 gallons. 3 * 96 = 288.
I think the formula is: P = P₀. e^(rt)
When P = 2P₀, the formula becomes 2P₀ =P₀.e^(rt)
Simplify by P₀, 2=e^(rt)
ln(2) = lne^(rt)
ln2 = rt.lne or lne =1 then ln2 = rt
