Answer:
How much is the discount?
=$70
What is the final sale price?=$210
Step-by-step explanation:
$280 =100%
$x =25%
$280 x 25%=7000/100=<u>70</u>
<u>280-70=210</u>
The values of the equation will be:
9. 12x - 1
10. -50 - x
11. -x + 14
12. x³ - 4y - 4
13. 8 - 6x
14. 288 - 1080x
15. 420 - y
16. 66 + 7y - 9x
<h3>How to compute the equation?</h3>
9. 4(3x+ 2) - 9
12x + 8 - 9
12x - 1
10. √144 – (62 –x)
12 - (62 - x)
-50 - x
11. (28 ÷ 4) – (x + 7)
7 - x + 7
= -x + 14
12. x³ – 4y - (6 + 2)
x³ - 4y - 4
13. 64 ÷ 8) – (x • 6)
= 8 - 6x
14. 72 (4 - 15x)
288 - 1080x
15. 4(√144 + 93)–y
4(12 + 93) - y
= 420 - y
16. 54 + 7y – (8 + 9x)
= 66 + 7y - 9x

<h3>
Answer: Choice A. $280.51</h3>
Work Shown:
A = P*(1+r/n)^(n*t) .... compound interest formula
A = 200(1+0.07/1)^(1*5) .... plug in given info
A = 200*(1.07)^5
A = 200*1.4025517307
A = 280.51034614
A = 280.51
