Answer:
4 different ways
Step-by-step explanation:
there are four different ways she can post it because there are four posters she want to hang on the wall.
The answer would be 8,000 because one row = 320 beads, and 25x320=8,000
1. If C is the cost function, then we have the equation of the function as
C(P) = P + 0.08P
P is the tax-free sales cost
we use 8% tax rate
3. If the price is $13.79
C($13.79) = 1.08 ($13.79) = $14.89
4. If the price is $59.95
C($59.95) = 1.08 ($59.95) = 64.75
5. C(P) = P + 0.08P
Simplifying,
C = 1.08P
