You purchase two bottles of and a hat. the hat costs $6.50. you pay 6% sales tax. you pay a total of $16.43. how much does one bottle of sunscreen cost?

price + 6%of price = 1.06*price total price = 16.43 divided by 1.06 gives a pretax total of 15.50 Subtract 6.50 for the hat leaves 9.00 if 2 bottles of sunscreen total 9.00, then each bottle cost $4.50.

hope this helps!

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
