(a) 34 copies
4520 = 1800 + 80c
2720 = 80c
34 = c
(b) $3,720
P = 1800 + 80(24)
P = 1800 + 1920
P = 3720

Step-by-step explanation:
3(2/3)
=3×2/3
=2×3/3
=2
Both of your answers are correct. In the first equation, if you were to substitute 3 for x, because you have to do exponents first, you have 3^2, which is 9, and 9*6 =54. If you were to substitute -3 for x again you would have to do the exponents first which would be -3^2 which is 9, and 9*6 = 54.
For the second question, if I substitute 0.75 for t, I get -9 + 18 + 7. This is equal to 16, and therefore the answer would be D. Hope this helps! :D. Let me know if you have questions about my explanation, and feel free to post more questions.
