Simplify each expression using the Order of Operations. a) (11 − 7)+ 3
b) 4 ∙ 3+ 10 ∙ 2
c) 35 ÷ 7 ∙ 4 − 15 ∙ 8

a)(11-7)+3

=(4)+3

=7

b)4.3+10.2

=12+20

=32

c)35÷7.4-15.8

=5.4-15.8

=20-120

=-100

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
