Answer: 30% discounted

Step-by-step explanation: 15.05 / 21.5 = 1

Subtract 15.05 / 21.5 from both sides and add Discount percent to both sides

discount percent=1 - 15.05 / 21.5 = 1 - 0.7 = 0.3 = 30% discounted

Undo the subtraction of 4 by adding 4 to both sides

$20 \ge v - 4$

$20+4 \ge v-4+4$

$24 \ge v$

$v \le 24$

This means v is less than or equal to 24.
In other words, v can be equal to 24 or it can be smaller than 24
