3r + 2(12r + 7) ≤ 5r – 8 i don't understand

3r+2(12r+7)<=5r-8 distribute by mult. 2 to everything in parenthesis

3r+24r+14<=5r-8  add 3r and 24 r

27r+14<=5r-8   subt 5r and subt 14

27r-5r<+-8-14

22r<+-22  divide by 22

22r/22<=-22/22

r<= -1

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
