An item is regularly priced at $35 . It is on sale for 80% off the regular price. What is the sale price?
Alexxx [7]

First change 80% to a decimal

80% = 80/100 = 0.80

Next, multiply 35 with 0.80

35 x 0.80 = 28

Next, subtract the number gotten (28) with the regular price (35)

35 - 28 = 7

-------------------------------------------------------------------------------------------------------------------

$7 is the sales price

Find f(0) and f(2) for the given exponential function. f(x) = (1/2)^-x
Aliun [14]
For 0 it will equal 1 because anything to the 0th power is 1 except 0 to the 0.

For 2, It will equal for because when you raise a fraction to the negative power you flip it and that gets rid of the negative number so then you will have 2 to the second and you will get 4.

f (0) = 1, f (2) = 4
