The histogram shows the scores on a recent science test. Using the histogram, select all of the true statements that describe the data. A. 00:00 Only 2 students scored less than 71 on the test. B. 00:00 More than half of the students scored 81 or better on the test. C. 00:00 More students scored between 91 and 100 on the test than scored between 71 and 80. D. 00:00 The same number of students scored between 81 and 90 on the test as scored between 61 and 80. E. 00:00 There were 12 students who scored 80 on the tes

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

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
