1 answer:
$84
$160 * 0.30 = $48
$160 - $48 = $112
$112. * 0.25 = $28
$112 - $28 = $84
Use what you know.
Guitar cost =$160 w/ 30% off
30% = 30/100 = 0.30.
30% off means 30% of the price $160 will be taken off so that is why I multiplied 160 by 0.30 (30/100).
30% of 160 is 48 so I subtracted 48 from 160 which equals $112.
With an extra 25% off I repeated the same steps above.
25/100 = 0.25
$112 * 0.25= $28
$112 - $28 = $84
If you need me to break it down more just let me know. I HOPE THIS HELPS

Answer:
35/2
Step-by-step explanation:
y ~ x
y=ky
7=2k
k=7/2
y=(7/2) × 5
y=35/2
Answer: The answer is the last one. Hope this helps!
we have M is durectly porpotional to r^2
so M=(k)r^2
and when r=2, m=14
so 14=(k)(2)^2
k=14/4 =7/2
so when r=12
m= (7/2)(12)^2 =(7/2)(144) = 504
it would be 7.2cm
because
45÷12=3.75
so thats the scale you use
and 27÷3.75 equals 7.2
