11. solve the inequality. show your work.
|r + 3| ≥ 7

r≤−10∪r≥4

|r+3|≥7

SOLUTION 1
r+3≥7
r≥4

SOLUTION 2

r+3≤−7
r≤−10

Since the two inequalities do not intersect when graphed, the solution set is

r≤−10∪r≥4 

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
