It is easier to solve by substitution.
Answer:
The total cost (in dollars) of p pens is C = 0.09 p
Step-by-step explanation:
The cost of each pen = 9 cents
Now, 1 cent = $0.01 cents
⇒ 9 cents = $0.09
So, the cost of 1 pen = $0.09
The number of pens purchased= p
Let the total cost of p pens = c
Also, the cost of p pens = p x ( Cost of 1 pen) = p ( $0.09) = 0.09 p
or, C = 0.09 p
Hence the total cost (in dollars) of p pens is C = 0.09 p.
(10 x 1) + (2 x 1) + (0.7 x 1) + ( 0.03 x 1) + (0.008 x 1)
2 points per goal, so 2g.
Add + 7 to that because she scored 7 points of free throws.
This means the answer would be A. 2g + 7.
F(-1) = (-1)^2 = 1
so if g(x) = 2x + 3 then g(f(-1)) = g(1) = 2(1) + 3 = 5
