Which sale gives the greatest percent discount? 20% off the original price. 75% of the original price. Original price reduced by
xxMikexx [17]

Answer:

75% off the original price

Step-by-step explanation:

No it doesn't depend on the original price.Why, because when it says original price reduced by 30%, that basically means 30% off the original price.Let's say the original price is $100, okay 20% off the original price is only $20 off, 75% off of the original price is $75 off, and to have the original price reduced by 30% means the price goes from 100 to 70, but the price would be $25 in this case after getting 75% off.

Write an exponential function in the form y=ab^x that goes through points (0, 18) and (2, 288)
Ede4ka [16]

y = abx

Point (1, 4): 4 = ab

Point (3, 16): 16 = ab^3

From 4=ab we have a = 4/b

Substitute into 2nd equation

16 = (4/b)b^3

16 = 4b^2

4 = b^2

2 = b

a = 4/b = 4/2 = 2

An exponential function that fits is: y = 2(2^x)

check: x=1; y = 2(21) = 4 ... point (1, 4)

x=3: y = 2(23) = 2(8) = 16 ... point (3, 16)
