X = 30
y = 120
30 x 4 = 120
120 + 120 = 240
240 + 120 = 360
The answer would be 36:18 and done
Let's rewrite the information then figure out the answer.
DVD: $9.00 originally but on sale with an 80% discount.
80%=0.80
9.00(0.80) = $7.20
$9.00 - $7.20 = $1.80
Thus, the sales price is: $1.80
Answer:
about 65 percentage is the correct answer
